Hi @pjain1 Thanks for asking. Yep, if desired task count becomes more than
the number of topic partitions, it will increase task number every
`dynamicCheckPeriod ` until meet taskCountMax instead of unlimited growth. So
that the increase behavior is controllable. Also to avoid this unnecessary
scenario maybe we can document the relationship between taskCountMax and kafka
partition like taskcount in IOConfig does? For example `The number of reading
tasks will be less than taskCountMax if taskCountMax > {numKafkaPartitions}.`
