Node Requirements for SingleStore DB Commands

Info

SingleStore Managed Service does not support this command.

SingleStore DB commands must be run on the appropriate type(s) of node in a SingleStore DB cluster.

When sync_permissions and enable_query_forwarding are set to ON, all Data Definition Language (DDL) commands can be forwarded from child aggregator to master. This list of requirements reflects this behavior. For more information about these variables, see the List of Engine Variables.

  • X = recommended to run on this type of node
  • P = possible (but not recommended) to run on this type of node
  • blank = cannot run on this type of node
