Hi there, what is the best way to trigger a job when all jobs in a backfilling are finished?

Hi Son, you could use the Dagster GraphQL API for this potentially. Here's an example query that returns the status of each run in a backfill:

```query backfillRuns {
  partitionBackfillOrError(backfillId: "your-backfill-id-here") {
    ... on PartitionBackfill {
      runs {
        status
      }
    }
  }
}```

Hi, but how can I apply this into sensor?

Ah ok, i see there are python lib for dagster graphql

But seems like `DagsterGraphQLClient` does not support for querying partitionBackfill tho

seems like it can using the `_execute` method, however, seems like you cannot use it with trigger because it doesn’t have enough filter. You can only filter it with `status` and `cursor`

You can query graphql without using the DagsterGraphQLClient - the DagsterGraphQLClient class is just for convenience. Libraries like <https://github.com/graphql-python/gql> can work as a client

Thanks for the information, I’ve just done a workaround with this
