Glue Throttling Exception when starting 15 Glue jobs in Parallel via Step Function

Question

We are using Step Functions for our ETL pipeline. The first step kicks off 21 jobs that each take about 1-3 minutes each consuming 5 DPUs. The Step Function fails with the below error when trying to run more than 15 Glue Jobs in parallel. We are using the arn:aws:states:::glue:startJobRun.sync task to invoke the jobs synchronously. Is there a quota I need to ask for an increase on? Kicking off 21 jobs in parallel seems pretty reasonable.

{ "resourceType": "glue", "resource": "startJobRun.sync", "error": "Glue.AWSGlueException", "cause": "Rate exceeded (Service: AWSGlue; Status Code: 400; Error Code: ThrottlingException; Proxy: null)" }

{
  "resourceType": "glue",
  "resource": "startJobRun.sync",
  "error": "Glue.AWSGlueException",
  "cause": "Rate exceeded (Service: AWSGlue; Status Code: 400; Error Code: ThrottlingException; 
 Proxy: null)"
}

Accepted Answer

Hi!  Good question.

For General Glue **Service Quotas** (Limits), please see here: https://docs.aws.amazon.com/general/latest/gr/glue.html

Default Glue Quotas include things like:
* Max concurrent job runs per account (50)
* Max jobs per trigger (50)

To increase those and other limits, you can open a Service Quota Increase Request.

For Throttling Exceptions (https://docs.aws.amazon.com/glue/latest/webapi/CommonErrors.html), I'm not sure on the exact limit where API calls will get limited - if that's the case, you may need to use exponential backoff to retry (I've seen this for other API calls): https://docs.aws.amazon.com/general/latest/gr/api-retries.html
