Motivation
The executor in
ManagedLedgerImpl
uses theMainWorkerPool
of bookKeeper, and both produce and consume use this thread pool.When there are a large number of partitions in the cluster and the cluster is busy, trim ledger will cause the produce latency to rise from hundreds of milliseconds to seconds. We found that a large number of tasks are stuck in the queue of the thread pool
Trim ledger is a thread-safe operation and has no latency requirements, so we'd better separate it from
MainWorkerPool
of bookKeeperModifications
