There are some use cases that require generic pre/post hook support:

  • Redis "join" command to create the cluster.
  • Elasticsearch drain the nodes during scale down.
  • Clickhouse replica distributed tables during scale up.

Even the generic concept of Readiness (after the start) could be modeled as a post hook.
A hook should be a one-off operation. Long running jobs like monitoring are not applied here.
