To rebalance the data in your database:

  7. Enter the directory for the Database Designer outputs (for example /tmp) and click OK.

  8. Accept the proposed K-safety value or provide a new value. Valid values are 0 to 2.

  9. Review the message and click Proceed to begin rebalancing data.

    The Database Designer modifies existing projections to rebalance data across all database nodes with the K-safety you provided. A script to rebalance data, which you can run manually at a later time, is also generated and resides in the path you specified; for example /tmp/extend_catalog_rebalance.sql.

    The terminal window notifies you when the rebalancing operation is complete.
