Create One Cluster

On this page

Note

Groups and projects are synonymous terms. Your {GROUP-ID} is the same as your project ID. For existing groups, your group/project ID remains the same. The resource and corresponding endpoints use the term groups.

Note

This feature is not available for M0 (Free Tier) clusters. For more information, see Atlas M0 (Free Tier) Limitations.

The Atlas API uses HTTP Digest Authentication. Provide a programmatic API public key and corresponding private key as the username and password when constructing the HTTP request.

For complete documentation on configuring API access for an Atlas project, see Configure Atlas API Access.

Considerations

  • For a given region in an Atlas project with multi-region clusters or clusters in multiple regions, there is a limit of 40 MongoDB nodes on all other regions in that project. This limit applies across all cloud service providers and can be raised upon request. GCP regions communicating with each other do not count against this limit.

    Example

    If an Atlas project has 20 nodes in Region A and 20 nodes in Region B, you can deploy no more than 20 additional nodes in that project in any given region. This limit applies even if Region A and Region B are backed by different cloud service providers.

    For Atlas projects where every cluster is deployed to a single region, you cannot create a multi-region cluster in that project if there are already 40 or more nodes in that single region unless you request that the limit be raised.

    Please contact Atlas support for questions or assistance raising this limit. To contact support, click Support from the left-hand navigation bar of the Atlas UI.

  • If your Atlas project contains a custom role that uses actions introduced in a specific MongoDB version, you must delete that role before creating clusters with an earlier MongoDB version.

Required Roles

To use this resource, your API Key must have either the Organization Owner or Project Owner roles.

status HTTP response code
envelope The expected response body
false

Request Body Parameters

Body Parameter Type Necessity Description
autoScaling object Optional Configure your cluster to automatically scale its storage and cluster tier. For more information on cluster auto-scaling, see Cluster Auto-Scaling.
autoScaling
.compute
 object Optional

Specifies whether the cluster automatically scales its cluster tier and whether the cluster can scale down.

Important

Cluster tier auto-scaling is not available for clusters using Low CPU or NVME storage classes.
autoScaling
.compute
.enabled
 boolean Optional

Specifies whether cluster tier auto-scaling is enabled. The default is false.

  • Set to true to enable cluster tier auto-scaling. If enabled, you must specify a value for providerSettings.autoScaling.compute.maxInstanceSize.
  • Set to false to disable cluster tier auto-scaling.
autoScaling
.compute
.scaleDownEnabled
 boolean Optional

Set to true to enable the cluster tier to scale down. This option is only available if autoScaling.compute.enabled is true.

If this option is enabled, you must specify a value for providerSettings.autoScaling.compute.minInstanceSize
autoScaling
.diskGBEnabled
 boolean Optional

Specifies whether disk auto-scaling is enabled. The default is true.

  • Set to true to enable disk auto-scaling.
  • Set to false to disable disk auto-scaling.

Note

Disk auto-scaling is subject to limitations based on the maximum amount of RAM for the selected cluster tier and the oplog size. See Customize Your Storage for details.
backupEnabled boolean Optional

Applicable only for M10+ clusters.

Set to true to enable Atlas continuous backups for the cluster.

Set to false to disable continuous backups for the cluster. Atlas deletes any stored snapshots. See the continuous backup Snapshot Schedule for more information.

You cannot enable continuous backups if you have an existing cluster in the project with Cloud Provider Snapshots enabled.

The default value is false.

Note

This option is not supported on sharded clusters running MongoDB 4.2. Sharded clusters running MongoDB 4.2 must use Cloud Provider Snapshots.
biConnector object Optional

Specifies BI Connector for Atlas configuration on this cluster.

The MongoDB Connector for Business Intelligence for Atlas (BI Connector) is only available for M10 and larger clusters.

The BI Connector is a powerful tool which provides users SQL-based access to their MongoDB databases. As a result, the BI Connector performs operations which may be CPU and memory intensive. Given the limited hardware resources on M10 and M20 cluster tiers, you may experience performance degradation of the cluster when enabling the BI Connector. If this occurs, upgrade to an M30 or larger cluster or disable the BI Connector.
biConnector
.enabled
 boolean Optional

Specifies whether or not BI Connector for Atlas is enabled on the cluster.

  • Set to true to enable BI Connector for Atlas.
  • Set to false to disable BI Connector for Atlas.
biConnector
.readPreference
 string Optional

Specifies the read preference to be used by BI Connector for Atlas on the cluster. Each BI Connector for Atlas read preference contains a distinct combination of readPreference and readPreferenceTags options. To learn more about BI Connector for Atlas read preferences, see BI Connector Read Preferences Table.

  • Set to "primary" to have BI Connector for Atlas read from the primary.

  • Set to "secondary" to have BI Connector for Atlas read from a secondary member. The preference defaults to this value if there are no analytics nodes in the cluster.

  • Set to "analytics" to have BI Connector for Atlas read from an analytics node. Default if the cluster contains analytics nodes.

    Note

    To set the readPreference value to "analytics", the cluster must have at least one analytics node.

    If the readPreference value is "analytics", you cannot remove all analytics nodes from the cluster.
clusterType string Conditional

Type of the cluster that you want to create.

When should you use clusterType?

Condition Necessity
You set replicationSpecs. Required
You are deploying Global Clusters. Required
You are deploying non-Global replica sets and sharded clusters. Optional

Accepted values include:

Value Cluster Type
REPLICASET replica set
SHARDED sharded cluster
GEOSHARDED Global Cluster
diskSizeGB number Conditional

Capacity, in gigabytes, of the host’s root volume. Increase this number to add capacity, up to a maximum possible value of 4096 (i.e., 4 TB). This value must be a positive integer.

When should you use diskSizeGB?

This setting:

  • Cannot be used with clusters with local NVMe SSDs
  • Cannot be used with Azure clusters
  • Must be used when replicationSpecs is set

The minimum disk size for dedicated clusters is 10GB for AWS and GCP, and 32GB for Azure. If you specify diskSizeGB with a lower disk size, Atlas defaults to the minimum disk size value.

Important

Atlas calculates storage charges differently depending on whether you choose the default value or a custom value. For details, see Storage Capacity.

Note

The maximum value for disk storage cannot exceed 50 times the maximum RAM for the selected cluster. If you require additional storage space beyond this limitation, consider upgrading your cluster to a higher tier.
encryptionAtRestProvider string Optional

Set the Encryption at Rest parameter to one of the following:

Specify AWS to enable Encryption at Rest using the Atlas project AWS Key Management System settings. The cluster must meet the following requirements:

Parameter Requirement
providerSettings
.instanceSizeName
 M10 or greater
backupEnabled false or omitted

For complete documentation on Encryption at Rest restrictions, see Prerequisites.

You must configure encryption at rest for the Atlas project before enabling it on any cluster in the project. For complete documentation on configuring Encryption at Rest, see Encryption at Rest using Customer Key Management.

Specify GCP to enable Encryption at Rest using the Atlas project GCP Key Management System settings. The cluster must meet the following requirements:

Parameter Requirement
providerSettings
.instanceSizeName
 M10 or greater
backupEnabled false or omitted

Specify NONE to disable Encryption at rest.
labels array Optional

Array containing key-value pairs that tag and categorize the cluster.

Each key and value has a maximum length of 255 characters.

"labels": [
   {
     "key": "example key",
     "value": "example value"
   }
 ]
name string Required Name of the cluster as it appears in Atlas. Once the cluster is created, its name cannot be changed.
mongoDBMajorVersion string Optional

Version of the cluster to deploy. Atlas supports the following MongoDB versions for M10+ clusters:

  • 3.4
  • 3.6
  • 4.0
  • 4.2

You must set this value to 4.0 if providerSettings.instanceSizeName is either M2 or M5.

Atlas always deploys the cluster with the latest stable release of the specified version. You can upgrade to a newer version of MongoDB when you modify a cluster.
numShards number Conditional

Positive integer that specifies the number of shards to deploy for a sharded cluster.

Important

If you use the replicationSpecs parameter, you must set numShards.

The possible values are 1 through 50, inclusive. The default value is 1.

  • If you specify a numShards value of 1 and a clusterType of SHARDED, Atlas deploys a single-shard sharded cluster.
  • If you specify a numShards value of 1 and a clusterType of REPLICASET, Atlas deploys a replica set.

Note

A sharded cluster with a single shard is not recommended for production environments. Single-shard sharded clusters do not provide the same high availability and horizontal scaling benefits as configurations with multiple shards.

For more information on sharded clusters, see Sharding in the MongoDB manual.

For details on how this setting affects costs, see Number of Servers.

Note

Do not include in the request body for Global Clusters.
pitEnabled boolean Optional Flag that indicates if the cluster uses Point-in-Time backups. If set to true, providerBackupEnabled must also be set to true.
providerBackupEnabled boolean Optional

Applicable only for M10+ clusters.

Flag that indicates if the cluster uses Cloud Provider Snapshots for backups.

If true, the cluster uses Cloud Provider Snapshots for backups. If providerBackupEnabled and backupEnabled are false, the cluster does not use Atlas backups.

You cannot enable cloud provider snapshots if you have an existing cluster in the project with Continuous Backups enabled.

Important

You must set this value to true for NVMe clusters.
providerSettings object Required Configuration for the provisioned servers on which MongoDB runs. The available options are specific to the cloud service provider.
providerSettings
.autoScaling
 object Conditional Object that contains the minInstanceSize and maxInstanceSize fields which specify the range of instance sizes to which your cluster can scale.
providerSettings
.autoScaling
.compute
 object Conditional Contains the minInstanceSize and maxInstanceSize fields which specify the range of instance sizes to which your cluster can scale. Required if autoScaling.compute.enabled is true.
providerSettings
.autoScaling
.compute
.minInstanceSize
 string Conditional Minimum instance size to which your cluster can automatically scale (e.g., M10). Required if autoScaling.compute.scaleDownEnabled is true.
providerSettings
.autoScaling
.compute
.maxInstanceSize
 string Conditional Maximum instance size to which your cluster can automatically scale (e.g., M40). Required if autoScaling.compute.enabled is true.
providerSettings
.backingProviderName
 string Conditional

Cloud service provider on which the server for a multi-tenant cluster is provisioned.

This setting is only valid when providerSetting.providerName is TENANT and providerSetting.instanceSizeName is M2 or M5.

The possible values are:

  • AWS - Amazon AWS
  • GCP - Google Cloud Platform
  • AZURE - Microsoft Azure
providerSettings
.diskIOPS
 number AWS Optional

Maximum input/output operations per second (IOPS) the system can perform. The possible values depend on the selected providerSettings.instanceSizeName and diskSizeGB.

This setting requires that providerSettings.instanceSizeName to be M30 or greater and cannot be used with clusters with local NVMe SSDs.

To view the possible range of IOPS values for the selected instance size and storage capacity:

  1. Open the Atlas web interface.
  2. Select Build a New Cluster.
  3. Under Cloud Provider & Region, select AWS.
  4. Under Cloud Provider & Region, select the region corresponding to your configured providerSettings.regionName.
  5. Under Cluster Tier, select the cluster tier corresponding to your configured providerSettings.instanceSizeName.
  6. Under Cluster Tier, set the Storage Capacity slider to your configured diskSizeGB. Alternatively, input the exact value of diskSizeGB in the input box to the right of the slider.

You can see the available IOPS range by checking the Provision IOPS box.

Note

If you set the diskIOPS value to a value higher than the default value for the selected volume size, Atlas automatically sets providerSettings.volumeType to PROVISIONED. If you manually set diskIOPS to the default value, you must specify providerSettings.volumeType to be either PROVISIONED or STANDARD.

The default value for providerSettings.diskIOPS is the same as the cluster tier’s Standard IOPS value, as viewable in the Atlas interface.

Changing this value affects the cost of running the cluster as described in the billing documentation.

Atlas enforces the following minimum ratios by cluster tier to facilitate consistent network performance with large datasets.

Disk Capacity to RAM:

  • < M40: 3:1
  • M40: 50:1
  • => M50: 100 to 1

Example

A cluster with 50 GB storage requires a value for IOPS of at least 150. To support 3 TB of disk capacity, you must select a cluster tier with at least 32 GB of RAM (M50 or higher).
providerSettings
.diskTypeName
 string Azure Required

Disk type of the server’s root volume for Azure instances. If omitted, Atlas uses the default disk type for the selected providerSettings.instanceSizeName.

The following table lists the possible values for this field, and their corresponding storage size.

diskTypeName Storage Size
P4 1 32GB
P6 64GB
P10 2 128GB
P20 512GB
P30 1024GB
P40 2048GB
P50 4095GB

1 Default for M20 and M30 Azure clusters

2 Default for M40+ Azure clusters
providerSettings
.encryptEBSVolume
 boolean AWS Optional

If enabled, the Amazon EBS encryption feature encrypts the server’s root volume for both data at rest within the volume and for data moving between the volume and the cluster.

Note

This setting is always enabled for clusters with local NVMe SSDs.

The default value is true.
providerSettings
.instanceSizeName
 string Required

Atlas provides different cluster tiers, each with a default storage capacity and RAM size. The cluster you select is used for all the data-bearing servers in your cluster tier. For definitions of data-bearing servers, see Number of Servers.

Important

If you are deploying a Global Cluster, you must choose a cluster tier of M30 or larger.

  • US_EAST_1
  • US_EAST_2
  • US_WEST_2
  • EU_WEST_1
  • EU_CENTRAL_1
  • AP_NORTHEAST_1

Atlas supports the following cluster tiers. Atlas supports deploying M2 and M5 tiers into a subset of available regions. The documentation for providersettings.regionName includes a list of these regions.

Cluster Tier Naming Conventions

Cluster tier names that are:

  • Appended with _NVME (M40_NVME for example) use direct attached NVMe storage for exceptional performance with the most I/O-intensive workloads.
  • Prepended with R instead of an M (R40 for example) run a low CPU version of the cluster.

Clusters with _NVME appended (for example: M40_NVME) use locally attached NVMe storage for exceptional performance with the most IO-intensive workloads.

providerSettings
.regionName
 string Conditional

Required if replicationSpecs array is empty

This field is required if you have not set any values in the replicationSpecs array.

Physical location of your MongoDB cluster. The region you choose can affect network latency for clients accessing your databases.

Do not specify this field when creating a multi-region cluster using the replicationSpec object or a Global Cluster with the replicationSpecs array.

During deployment of an M10+ dedicated paid cluster, Atlas creates a VPC for the selected provider and region or regions if no existing VPC or VPC peering connection exists for that provider and region. Atlas assigns the VPC a Classless Inter-Domain Routing (CIDR) block.

For clusters deployed on AWS, if you want to create a VPC peering connection to an AWS VPC and require a specific CIDR block for a given region, you must create a VPC connection before deploying the cluster. See Set up a Network Peering Connection for for complete documentation on VPC peering connections.

Important

Multi-region clusters require one VPC peering connection for each region. MongoDB nodes can use only the peering connection that resides in the same region as the nodes to communicate with the peered VPC.

Select your cloud provider’s tab for example cluster region names:

  • US_EAST_1
  • US_WEST_2
  • EU_WEST_1

For a complete list of supported AWS regions, see Amazon Web Services (AWS).

providerSettings
.volumeType
 string AWS Optional

Possible values are:

Volume Type providerSettings.diskIOPS Value
STANDARD Must not exceed the default IOPS rate for the selected volume size.
PROVISIONED Must fall within the allowable IOPS range for the selected volume size.
replicationFactor number Optional

Use replicationSpecs

replicationFactor is deprecated. Use replicationSpecs.

Number of replica set members. Each member keeps a copy of your databases, providing high availability and data redundancy. The possible values are 3, 5, or 7. The default value is 3.

Do not specify this field when creating a multi-region cluster using the replicationSpec object.

If your cluster is a sharded cluster, each shard is a replica set with the specified replication factor.

For information on how the replication factor affects costs, see Number of Servers. For more information on MongoDB replica sets, see Replication in the MongoDB manual.

Atlas ignores this value if you pass the replicationSpec object.
replicationSpec object Optional

Use replicationSpecs

replicationSpec is deprecated. Use replicationSpecs.

Configuration of each region in a multi-region cluster. Each element in this object represents a region where Atlas deploys your cluster.

For single-region clusters, you can either specify the providerSettings.regionName and replicationFactor, or you can use the replicationSpec object to define a single region.

For multi-region clusters, omit the providerSettings.regionName field.

For Global Clusters, specify the replicationSpecs parameter rather than a replicationSpec parameter.

Important

If you use replicationSpec, you must specify a minimum of one replicationSpec.<region> object and sort each .<region> object by .<region>.priority in descending order.

Use the replicationSpecs parameter to create a Global Cluster.

Note

You cannot specify both the replicationSpec and replicationSpecs parameters in the same request body.
replicationSpec
.<region>
 object Required

Physical location of the region. Replace <region> with the name of the region. Each <region> object describes the region’s priority in elections and the number and type of MongoDB nodes Atlas deploys to the region.

Important

If you use replicationSpec, you must specify a minimum of one replicationSpec.<region> object and sort each .<region> object by .<region>.priority in descending order.

Select your cloud provider’s tab for example cluster region names:

  • US_EAST_1
  • US_WEST_2
  • EU_WEST_1

  • CENTRAL_US
  • WESTERN_EUROPE
  • EASTERN_ASIA_PACIFIC

For a complete list of supported GCP regions, see Google Cloud Platform (GCP).

For each <region> object, you must specify the analyticsNodes, electableNodes, priority, and readOnlyNodes fields. For information on cross-region node limits, see Considerations.

During deployment of an M10+ dedicated paid cluster, Atlas creates a VPC for the selected provider and region or regions if no existing VPC or VPC peering connection exists for that provider and region. Atlas assigns the VPC a Classless Inter-Domain Routing (CIDR) block.

For clusters deployed on AWS, if you want to create a VPC peering connection to an AWS VPC and require a specific CIDR block for a given region, you must create a VPC connection before deploying the cluster. See Set up a Network Peering Connection for for complete documentation on VPC peering connections.

Important

Multi-region clusters require one VPC peering connection for each region. MongoDB nodes can use only the peering connection that resides in the same region as the nodes to communicate with the peered VPC.
replicationSpec
.<region>
.electableNodes
 number Optional

Number of electable nodes for Atlas to deploy to the region. Electable nodes can become the primary and can facilitate local reads.

The total number of electableNodes across all replicationSpec.<region> object must be 3, 5, or 7.

Specify 0 if you do not want any electable nodes in the region.

You cannot create electable nodes if the replicationSpec.<region>.priority is 0.
replicationSpec
.<region>
.priority
 number Optional

Election priority of the region. For regions with only replicationSpec.<region>.readOnlyNodes, set this value to 0.

For regions where replicationSpec.<region>.electableNodes is at least 1, each replicationSpec.<region> must have a priority of exactly one (1) less than the previous region. The first region must have a priority of 7. The lowest possible priority is 1.

The priority 7 region identifies the Preferred Region of the cluster. Atlas places the primary node in the Preferred Region. Priorities 1 through 7 are exclusive - no more than one region per cluster can be assigned a given priority.

Example

If you have three regions, their priorities would be 7, 6, and 5 respectively. If you added two more regions for supporting electable nodes, the priorities of those regions would be 4 and 3 respectively.
replicationSpec
.<region>
.readOnlyNodes
 number Optional

Number of read-only nodes for Atlas to deploy to the region. Read-only nodes can never become the primary, but can facilitate local-reads.

Specify 0 if you do not want any read-only nodes in the region.
replicationSpec
.<region>
.analyticsNodes
 number Optional

The number of analytics nodes for Atlas to deploy to the region. Analytics nodes are useful for handling analytic data such as reporting queries from BI Connector for Atlas. Analytics nodes are read-only, and can never become the primary.

If you do not specify this option, no analytics nodes are deployed to the region.

autoScaling
.compute
.enabled
 boolean Specifies whether cluster tier auto-scaling is enabled.
autoScaling
.compute
.scaleDownEnabled
 boolean Specifies whether the cluster tier can scale down.
autoScaling
.diskGBEnabled
 boolean Specifies whether disk auto-scaling is enabled.

biConnector object

Information on whether BI Connector for Atlas is enabled or disabled for the cluster.

The MongoDB Connector for Business Intelligence for Atlas (BI Connector) is only available for M10 and larger clusters.

The BI Connector is a powerful tool which provides users SQL-based access to their MongoDB databases. As a result, the BI Connector performs operations which may be CPU and memory intensive. Given the limited hardware resources on M10 and M20 cluster tiers, you may experience performance degradation of the cluster when enabling the BI Connector. If this occurs, upgrade to an M30 or larger cluster or disable the BI Connector.

The biConnector object includes the following fields:

Field Description
enabled
true if BI Connector for Atlas is enabled.
false if BI Connector for Atlas is disabled.
readPreference
"primary" if BI Connector for Atlas reads from the primary.
"secondary" if BI Connector for Atlas reads from a secondary.
"analytics" if BI Connector for Atlas reads from an analytics node.
clusterType string

Specifies the type of the cluster:

Value Description
REPLICASET replica set
SHARDED sharded cluster
GEOSHARDED Global Cluster
diskSizeGB number

Capacity, in gigabytes, of the host’s root volume. Increase this number to add capacity, up to a maximum possible value of 4096 (i.e., 4 TB). This value must be a positive integer.

When should you use diskSizeGB?

This setting:

  • Cannot be used with clusters with local NVMe SSDs
  • Cannot be used with Azure clusters
  • Must be used when replicationSpecs is set

The minimum disk size for dedicated clusters is 10GB for AWS and GCP, and 32GB for Azure. If you specify diskSizeGB with a lower disk size, Atlas defaults to the minimum disk size value.

Important

Atlas calculates storage charges differently depending on whether you choose the default value or a custom value. For details, see Storage Capacity.

Note

The maximum value for disk storage cannot exceed 50 times the maximum RAM for the selected cluster. If you require additional storage space beyond this limitation, consider upgrading your cluster to a higher tier.
encryptionAtRestProvider string

Encryption at Rest is enabled or disabled.

To learn more about Encryption-at-Rest restrictions, see Prerequisites.

You must configure encryption at rest for the Atlas project before enabling it on any cluster in the project. To learn more about configuring Encryption at Rest, see Customer Key Management with AWS KMS.
groupId string Unique identifier of the project the cluster belongs to.
id string Unique identifier of the cluster.
labels array Array containing key-value pairs that tag and categorize the cluster.
mongoDBVersion string Version of MongoDB the cluster runs, in <major version>.<minor version> format.
mongoDBMajorVersion string

Major version of MongoDB the cluster runs:

  • 3.4
  • 3.6
  • 4.0
  • 4.2
mongoURI string

Base connection string for the cluster.

Atlas only displays this field after the cluster is operational, not while it builds the cluster.
mongoURIUpdated string Timestamp in ISO 8601 date and time format in UTC when the connection string was last updated. The connection string changes if you update any of the other values.
mongoURIWithOptions string

connection string for connecting to the Atlas cluster. Includes the replicaSet, ssl, and authSource query parameters in the connection string with values appropriate for the cluster.

To review the connection string format, see the connection string format documentation. To add MongoDB users to a Atlas project, see Configure MongoDB Users.

Atlas only displays this field after the cluster is operational, not while it builds the cluster.
name string Name of the cluster as it appears in Atlas.
numShards number

Positive integer that specifies the number of shards for a sharded cluster.

If this is set to 1, the cluster is a replica set.

If this is set to 2 or higher, the cluster is a sharded cluster with the number of shards specified.

For details on how this setting affects costs, see Number of Servers.

The possible values are 1 through 12.

Note

Atlas doesn’t return this value in the response body for Global Clusters.
paused boolean Flag that indicates whether the cluster is paused or not.
pitEnabled boolean Flag that indicates if the cluster uses Point-in-Time backups. If set to true, providerBackupEnabled must also be set to true.
providerBackupEnabled boolean

Applicable only for M10+ clusters.

Flag that indicates if the cluster uses Cloud Provider Snapshots for backups.

If true, the cluster uses Cloud Provider Snapshots for backups. If providerBackupEnabled and backupEnabled are false, the cluster does not use Atlas backups.
providerSettings object Configuration for the provisioned servers on which MongoDB runs. The available options are specific to the cloud service provider.
providerSettings
.autoScaling

providerSettings
.regionName
 string

Physical location of your MongoDB cluster. The region you choose can affect network latency for clients accessing your databases.

For a complete list of region name values, refer to the the cloud provider reference pages:

For multi-region clusters, see replicationSpec.<region>.
providerSettings
.instanceSizeName
 string

Name of the cluster tier used for the Atlas cluster.

Atlas supports the following cluster tiers. Atlas supports deploying M2 and M5 tiers into a subset of available regions. The documentation for providersettings.regionName includes a list of these regions.

Cluster Tier Naming Conventions

Cluster tier names that are:

  • Appended with _NVME (M40_NVME for example) use direct attached NVMe storage for exceptional performance with the most I/O-intensive workloads.
  • Prepended with R instead of an M (R40 for example) run a low CPU version of the cluster.

Clusters with _NVME appended (for example: M40_NVME) use locally attached NVMe storage for exceptional performance with the most IO-intensive workloads.

replicationFactor number

Number of replica set members. Each member keeps a copy of your databases, providing high availability and data redundancy.

For multi-region clusters, add the total number of replicationSpec.<region>.electableNodes to calculate the replication factor of the cluster.

If your cluster is a sharded cluster, each shard is a replica set with the specified replication factor.

For information on how the replication factor affects costs, see Number of Servers. For more information on MongoDB replica sets, see Replication in the MongoDB manual.

The possible values are 3, 5, or 7.
replicationSpec object Configuration of each region in the cluster. Each element in this object represents a region where Atlas deploys your cluster.
replicationSpec
.<region>
 object

Physical location of the region. The <region> string corresponds to a region where Atlas deploys your cluster.

Each <region> object describes the region’s priority in elections and the number and type of MongoDB nodes Atlas deploys to the region.
replicationSpec
.<region>
.analyticsNodes
 number Number of analytics nodes in the region. Analytics nodes are useful for handling analytic data such as reporting queries from BI Connector for Atlas. Analytics nodes are read-only, and can never become the primary.
replicationSpec
.<region>
.electableNodes
 number Number of electable nodes in the region. Electable nodes can become the primary and can facilitate local reads.
replicationSpec
.<region>
.priority
 number

Election priority of the region. The highest possible priority is 7, which identifies the Preferred Region of the cluster. Atlas places the primary node in the Preferred Region. The lowest possible priority is 0, which identifies a read-only region.

You can have any number of priority 0 read only regions. Priorities 1 through 7 are exclusive: only one region per cluster can be assigned a given priority.
replicationSpec
.<region>
.readOnlyNodes
 number Number of read-only nodes in the region. Read-only nodes can never become the primary member, but can facilitate local reads.
replicationSpecs array Configuration for each zone in a Global Cluster. Each object in this array represents a zone where Atlas deploys nodes for your Global Cluster.
replicationSpecs[n]
.id
 string Unique identifier of the replication object.
replicationSpecs[n]
.zoneName
 string Name for the zone.
replicationSpecs[n]
.numShards
