* WIP * Make release concurrency system extremely simple, everything just releases all the time * update the deadlock detection to use the new lockedQueueReleaseConcurrencyOnWaitpoint column * WIP new release concurrency system * Remove releaseConcurrency and releaseConcurrencyOnWaitpoint Also removed deadlock detection, and added environment burst concurrency * Added new DEQUEUED status Cleaned up the API run statuses, including now detecting new clients and not breaking older clients by adding an API version header to all requests * Introduce the new "current dequeued concurrency set" * Remove QUEUED_EXECUTING because we no longer "eagerly" release before checkpointing * Remove waitpoint test for QUEUED_EXECUTING * Add isWaiting * Add changeset * Use createdAt for ordering realtime runs instead of number * Clarify the envCurrentDequeuedKey usage * mock the db.server file to fix the tests * Updated changset "EXECUTED" -> "EXECUTING" --------- Co-authored-by: Matt Aitken <matt@mattaitken.com>
@trigger.dev/database
This is the internal database package for the Trigger.dev project. It exports a generated prisma client that can be instantiated with a connection string.
How to switch branches when you've done migrations
Sometimes you've applied migrations and then want to switch branches without wiping out your local database.
To do this you can run the following command:
DB_VOLUME=database-data-alt pnpm run docker
This will switch to the alt volume for your local database. This database will be blank if you haven't switched to this volume before, so you'll need to follow the normal steps (in the Contributing guide) to get setup, e.g. apply migrations and seed.
To switch back to the original volume, run the following command:
pnpm run docker
How to add a new index on a large table
- Modify the Prisma.schema with a single index change (no other changes, just one index at a time)
- Create a Prisma migration using
cd internal-packages/database && pnpm run db:migrate:dev --create-only - Modify the SQL file: add IF NOT EXISTS to it and CONCURRENTLY:
CREATE INDEX CONCURRENTLY IF NOT EXISTS "JobRun_eventId_idx" ON "JobRun" ("eventId");
- Don’t apply the Prisma migration locally yet. This is a good opportunity to test the flow.
- Manually apply the index to your database, by running the index command.
- Then locally run
pnpm run db:migrate:deploy
Before deploying
Run the index creation before deploying
CREATE INDEX CONCURRENTLY IF NOT EXISTS "JobRun_eventId_idx" ON "JobRun" ("eventId");
These commands are useful:
-- creates an index safely, this can take a long time (2 mins maybe)
CREATE INDEX CONCURRENTLY IF NOT EXISTS "JobRun_eventId_idx" ON "JobRun" ("eventId");
-- checks the status of an index
SELECT * FROM pg_stat_progress_create_index WHERE relid = '"JobRun"'::regclass;
-- checks if the index is there
SELECT * FROM pg_indexes WHERE tablename = 'JobRun' AND indexname = 'JobRun_eventId_idx';
Now, when you deploy and prisma runs the migration, it will skip the index creation because it already exists. If you don't do this, there will be pain.
