Description

Jira Link: DB-3059

Description

Steps:

  1. Create a snapshot schedule.
  2. Delete snapshot_schedule.
  3. List all snapshot schedules via list_snapshot_schedules.

Observation:

If we keep on hitting list_snapshot_schedules, it will list deleted one as well for around 5 to 10 seconds. There is latency. Is this async call? Should we make it sync call?

Contributor guide

Research direction
Investigate the asynchronous deletion of snapshot schedules in DocDB. Determine why list snapshot schedules still returns deleted schedules for a few seconds. Consider making deletion synchronous or adding a sync mechanism to eliminate the latency.
