defineConcurrencyLimit()

Define a concurrency limit group to control the concurrency of your jobs.

These are the docs for Trigger.dev v2 which will be deprecated on January 31st, 2025. You probably want the v3 docs.

You can control the concurrency of run executions for a group of jobs using a concurrency limit group.

example

const concurrencyLimit = client.defineConcurrencyLimit({
  id: `test-shared`,
  limit: 5, // Limit all jobs in this group to 5 concurrent executions
});

client.defineJob({
  id: `test-job-1`,
  name: `Test Job 1`,
  version: "1.0.0",
  trigger: eventTrigger({
    name: "test",
  }),
  concurrencyLimit,
});

client.defineJob({
  id: `test-job-2`,
  name: `Test Job 2`,
  version: "1.0.0",
  trigger: eventTrigger({
    name: "test",
  }),
  concurrencyLimit,
});
