Cron
Schedule Recurring Jobs with Cron Syntax in Postgres
Supabase Cron is a Postgres Module that simplifies scheduling recurring Jobs with cron syntax and monitoring Job runs inside Postgres.
Cron Jobs can be created via SQL or the Integrations -> Cron interface inside the Dashboard, and can run anywhere from every second to once a year depending on your use case.
Every Job can run SQL snippets or database functions with zero network latency or make an HTTP request, such as invoking a Supabase Edge Function, with ease.
For best performance, we recommend no more than 8 Jobs run concurrently. Each Job should run no more than 10 minutes.
How does Cron work?
Under the hood, Supabase Cron uses the pg_cron Postgres database extension which is the scheduling and execution engine for your Jobs.
The extension creates a cron schema in your database and all Jobs are stored on the cron.job table. Every Job's run and its status is recorded on the cron.job_run_details table.
The Supabase Dashboard provides and interface for you to schedule Jobs and monitor Job runs. You can also do the same with SQL.
