Change Data Capture is a feature that enables users to monitor data in a selected table and get notifications whenever it's changed.

This is a top-level issue for the whole feature which will be implemented in smaller steps:

  1. Minimal CDC version that logs only primary key for each change #4986
  2. Logging of mutation itself #4987
  3. Logging pre-image of data in the moment just before the change #4988
  4. Handling cluster topology changes #4989
  5. Handling schema changes of the observed table #4990
  6. Making sure schema of CDC Log and CDC Description can't be changed manually by the user #4991
  7. Implement post-image of data #4992
