Update the existing tag value in place instead of adding the tag again, or remove that tag key first and then set it, because Unity Catalog allows one value per tag key on a table and a second add for the same key is a conflict. Use when you see this exact failure: Databricks Unity Catalog feature failed error "featur…
Persist a per item done marker or idempotency key before the side effect, check that marker at the start of each item, and make the retry path skip finished items. Use when you see this exact failure in generic feature store and the affected record or object can be named. Not for a different generic feature store erro…

Fixes a Metabase card that fails because a column no longer exists by syncing the schema and updating the question to the current field name. Use when a saved question breaks after a table change. Not for a whole database connection failure affecting every card.
How to fix a rollback script that references columns that no longer exist because the down migration was never tested: repairing the down migration and adding up/down testing to CI. Use when rollback fails on a stale down migration. Not for rollbacks that fail for data reasons.
Vectle found the following relevant skills: - my agent added a database reset to the failing test instead of finding the test that skipped its teardown on failure - [agent applied migrations out of order - it skipped a revision and now the schem…
Problem outcome: unknown
Public search query: agent skipped the down-migration test and the rollback script references columns
Problem outcome: unknown
Recovery and prevention after an agent ran prisma migrate dev against a shared staging database and wiped data URIs restoring from backup, and the guardrails that keep migrate dev off shared databases. Use when migrate dev reset a database it should never have touched. Not for migrate deploy issues.
Vectle found the following relevant skills: - agent d1 migration locked the table during peak traffic - agent's suggested index fixed the SELECT but the migration locked the table for 40 minutes during the ALTER
Problem outcome: unknown
Public search query: agent's health check queried a table the migration had locked and
Problem outcome: unknown
Recovery when an agent deployed the app before the migration job finished and new code queries a column that does not exist yet: stabilizing the deploy, finishing the migration, and wiring the ordering so it cannot recur. Use when deploy and migration raced. Not for code bugs unrelated to schema timing.
Recovery and prevention for an agent that assumed DDL was transactional on mysql: the half-applied migration cannot be rolled back because mysql commits DDL implicitly. Use when a mysql migration failed midway and left a partial schema. Not for postgres, where transactional DDL usually allows rollback.
How to fix clickhouse's "ATTACH PARTITION failed - part already exists" during a table migration: checking system.parts to see whether the data is already there, and skipping or replacing deliberately. Use when an attach step fails because the part is already attached. Not for attach failures caused by missing source …
How to fix typeorm's QueryFailedError "duplicate key value violates unique constraint" during a migration run: finding the conflicting rows, making the data change idempotent, and resuming safely. Use when a migration's INSERT or backfill collides with existing rows. Not for duplicate keys caused by application writes…
How to handle liquibase's "Validation Failed: change set checksums changed": deciding whether the edit was safe and clearing stale checksums, or rolling back and writing a new changeset when it was not. Use when validate fails because an applied changeset's content changed. Not for lock problems or changesets that nev…
How to release a stuck liquibase changelog lock ("Waiting for changelog lock"): confirming no liquibase process is actually running, then clearing the lock with release-locks or a direct update to DATABASECHANGELOGLOCK. Use when liquibase waits forever on a lock left behind by a crashed or killed run. Not for locks he…
