HTTP interface for jobs

The HTTP API for jobs lets you access the results of asynchronously executed requests and check the status of such jobs

Get the results of an async job

put /_api/job/{job-id}
Returns the result of an async job identified by job-id. If the async job result is present on the server, the result will be removed from the list of result. That means this method can be called for each job-id once. The method will return the original job result’s headers and body, plus the additional HTTP header x-arango-async-job-id. If this header is present, then the job was found and the response contains the original job’s result. If the header is not present, the job was not found and the response contains status information from the job manager.
Path Parameters
  • The async job id.

Query Parameters
    Responses
    • is returned if the job requested via job-id is still in the queue of pending (or not yet finished) jobs. In this case, no x-arango-async-id HTTP header will be returned.

    • is returned if no job-id was specified in the request. In this case, no x-arango-async-id HTTP header will be returned.

    • is returned if the job was not found or already deleted or fetched from the job result list. In this case, no x-arango-async-id HTTP header will be returned.

    Examples

    Not providing a job-id:

    curl -X PUT --header 'accept: application/json' --dump - http://localhost:8529/_api/job
    Show output

    Providing a job-id for a non-existing job:

    curl -X PUT --header 'accept: application/json' --dump - http://localhost:8529/_api/job/notthere
    Show output

    Fetching the result of an HTTP GET job:

    curl -X PUT --header 'x-arango-async: store' --header 'accept: application/json' --dump - http://localhost:8529/_api/version
    
    curl -X PUT --header 'accept: application/json' --dump - http://localhost:8529/_api/job/67821
    Show output

    Fetching the result of an HTTP POST job that failed:

    curl -X PUT --header 'x-arango-async: store' --header 'accept: application/json' --data-binary @- --dump - http://localhost:8529/_api/collection
    {
      "name": " this name is invalid "
    }
    
    curl -X PUT --header 'accept: application/json' --dump - http://localhost:8529/_api/job/67849
    Show output

    Cancel an async job

    put /_api/job/{job-id}/cancel
    Cancels the currently running job identified by job-id. Note that it still might take some time to actually cancel the running async job.
    Path Parameters
    • The async job id.

    Query Parameters
      Responses
      • cancel has been initiated.

      • is returned if no job-id was specified in the request. In this case, no x-arango-async-id HTTP header will be returned.

      • is returned if the job was not found or already deleted or fetched from the job result list. In this case, no x-arango-async-id HTTP header will be returned.

      Examples

      curl -X POST --header 'x-arango-async: store' --header 'accept: application/json' --data-binary @- --dump - http://localhost:8529/_api/cursor
      {
        "query": "FOR i IN 1..10 FOR j IN 1..10 LET x = sleep(1.0) FILTER i == 5 && j == 5 RETURN 42"
      }
      
      curl --header 'accept: application/json' --dump - http://localhost:8529/_api/job/pending
      
      curl -X PUT --header 'accept: application/json' --dump - http://localhost:8529/_api/job/67886/cancel
      
      curl --header 'accept: application/json' --dump - http://localhost:8529/_api/job/pending
      Show output

      Delete async job results

      delete /_api/job/{job-id}
      Deletes either all job results, expired job results, or the result of a specific job. Clients can use this method to perform an eventual garbage collection of job results.
      Path Parameters
      • The ID of the job to delete. The ID can be

        • all Deletes all jobs results. Currently executing or queued async jobs are not stopped by this call.
        • expired Deletes expired results. To determine the expiration status of a result, pass the stamp query parameter. stamp needs to be a Unix timestamp, and all async job results created before this time are deleted.
        • A numeric job ID In this case, the call removes the result of the specified async job. If the job is currently executing or queued, it is not aborted.

      Query Parameters
      • A Unix timestamp specifying the expiration threshold for when the job-id is set to expired.

      Responses
      • is returned if the deletion operation was carried out successfully. This code will also be returned if no results were deleted.

      • is returned if job-id is not specified or has an invalid value.

      • is returned if job-id is a syntactically valid job ID but no async job with the specified ID is found.

      Examples

      Deleting all jobs:

      curl -X PUT --header 'x-arango-async: store' --header 'accept: application/json' --dump - http://localhost:8529/_api/version

      List async jobs by status or get the status of specific job

      get /_api/job/{job-id}

      This endpoint returns either of the following, depending on the specified value for the job-id parameter:

      • The IDs of async jobs with a specific status
      • The processing status of a specific async job
      Path Parameters
      • If you provide a value of pending or done, then the endpoint returns an array of strings with the job IDs of ongoing or completed async jobs.

        If you provide a numeric job ID, then the endpoint returns the status of the specific async job in the form of an HTTP reply without payload. Check the HTTP status code of the response for the job status.

      Query Parameters
      • The maximum number of job IDs to return per call. If not specified, a server-defined maximum value is used. Only applicable if you specify pending or done as job-id to list jobs.

      Responses
      • is returned if the job with the specified job-id has finished and you can fetch its results, or if your request for the list of pending or done jobs is successful (the list might be empty).

      • is returned if the job with the specified job-id is still in the queue of pending (or not yet finished) jobs.

      • is returned if you specified an invalid value for job-id or no value.

      • is returned if the job cannot be found or is already fetched or deleted from the job result list.

      Examples

      Querying the status of a done job:

      curl -X PUT --header 'x-arango-async: store' --header 'accept: application/json' --dump - http://localhost:8529/_api/version
