Complex migration hook

The hook is used to check new migration files for the presence of large tables.

Migrations that include large tables must be tested on a copy of the production database and must contain the comments:

  • # migration tested on prod database
  • # migration_duration: {n} where n is the migration execution time in minutes (integer only).

A downtime migration is a migration whose execution time exceeds 1 minute. Such migrations will be marked with the "_downtime" postfix.

Hook args:

  • --tables - names of big tables separated by commas. These tables will be validated by the hook.
  • --min-revision - min revision number of migration after which the hook will perform the validation.
  • --migrations-dir - path to migrations directory. Do not include "versions" and "old_versions" in path
