Balance tablet leaders across TServers

    XMLWordPrintableJSON

Details

    Description

      The number of leader tablets per tablet server can become imbalanced over time, putting additional pressure on a few nodes.

      A CLI tool or an extension to the existing balancer should be added to take care of this.

      Currently the only option is running leader_step_down manually.
