Unsupported Commands in M10+ Clusters

Atlas requires clients to authenticate to access an Atlas cluster. Atlas provides a curated list of Database User Privileges. These privileges provide access to a subset of MongoDB commands.

The following table lists the most common commands and shell methods that database user privileges do not support. The functionality provided by these commands are largely subsumed by Atlas, or are restricted to ensure cluster stability and performance.

Commands Shell Method
  sh.disableBalancing()
  sh.enableBalancing()
