RESTORE REDUNDANCY

Restore redundancy by replicating any partitions with only one instance.

Syntax

RESTORE REDUNDANCY ON db_name

Remarks

  • db_name is the name of a MemSQL database.
  • Similarly, REBALANCE PARTITIONS restores redundancy by replicating any partitions with only one instance. However, REBALANCE PARTITIONS then does the additional step of moving partitions around to ensure balance across all the leaves.
  • This command must be run on the master aggregator node (see Node Requirements for MemSQL Commands ).
Info

This MemSQL feature is only available in MemSQL Enterprise Edition. MemSQL Enterprise Edition includes 24x7 support and several enterprise-only features for critical deployments. For more information about MemSQL Developer and MemSQL Enterprise, see the MemSQL Editions page.
