> During integration testing NiFi with Druid, I noticed a constant, overhead in the realtime index tasks: eg.: even if i set the
> {code:java}
> druid-cs-window-period=PT1M{code}
> the task duration was still at 426726ms (~7 minutes)
> 5 of that 7 minutes were due to firehose's grace period.
> My suggestion is to expose `druidBeam.firehoseGracePeriod` ([https://github.com/druid-io/tranquility/blob/master/docs/configuration.md#properties]) to the controller service: DruidTranquilityController, and build it into
> [https://github.com/apache/nifi/blob/3696b5bfcf0bd9e12ee4e9472f3413a93c9c0fcd/nifi-nar-bundles/nifi-druid-bundle/nifi-druid-controller-service/src/main/java/org/apache/nifi/controller/druid/DruidTranquilityController.java#L452-L457] the beam config.
> Currently this constant takes the default value of 5 minutes, causing a constant overhead on each of the indexing tasks initiated by NiFi, no matter how few/small the workload window.
