PeerDB allows you to pause and resume a Change-Data Capture mirror.
  1. As of today, mirrors can only be paused during CDC and not during initial load or query replication.
  2. The PostgreSQL source replication slot will still exist and it will continue to grow as long the mirror is paused.
  3. Pausing a mirror enables you to then add tables to the CDC mirror, along with editing the Sync Interval and Pull Batch Size.

​
Why would I pause a mirror ?

  1. You could want to run some initial set of validations and analysis on synced data.
  2. You could want to edit the mirror.
