In AWS kinesis data analytics application , integrated the Apache flink application. In apache flink dashboard Task Managers count is 2 but need to add 2 more Task Managers in apache flink for improving performance.

You can increase parallelism of the job and/or decrease slots number. Ex:

  • parallelism 4 2 slots => Flink will allocate 2 TM
  • parallelism 4 1 slot => Flink will allocate 4 TM

  • These things are probably not present on kinesis. Kinesis has Parallelism and parallelism per KPU. Which then converts in to KPU. Is there a way to allocate task managers using these units in Amazon Kinesis.? – Nikhil Pandit Jul 29 '22 at 13:18
