Confirming that the migration has not finished or have not taken place

First check the node_events table (i.e. SELECT * FROM node_events LIMIT 1;). There should be a “repo” column. If there is not the migration has not taken place. The migration will add the “repo” column.

Second check the migration_status table. There should be a row with “event-table-repo-key-migration”. If there is not the migration has not taken place.
