ASF subversion and git services commented on KUDU-2612: ------------------------------------------------------- Commit fa5fdd8532efa3a634eaba1fea4552f66d881623 in kudu's branch refs/heads/master from Alexey Serbin [ https://gitbox.apache.org/repos/asf?p=kudu.git;h=fa5fdd8 ] KUDU-2612: non-zero queue size for txn-commit pool I found my new tests for the automatic txn participant registration often hit the following CHECK(): F0212 06:49:33.448449 611 txn_status_manager.cc:371] Check failed: _s.ok() Bad status: Service unavailable: Thread pool is at capacity (10/10 tasks running, 2/0 tasks queued) As I can see, the code in CommitTasks::Schedule{AbortTxn,FinalizeCommit}Write() doesn't handle the condition of running out of the "txn-commit" pool's queue. That means the pool is supposed to have an unlimited queue size, like other pools which exhibit similar behaviour: e.g., the pool for removing tablets, the pool for opening tablets, etc. Indeed, since the number of concurrently opened multi-row transactions isn't limited, TxnStatusManager should be able handle the case when many transactions are being aborted and committed simultaneously. This patch removes the queue size limit for the "txn-commit" pool (effectively setting it to INT_MAX), mirroring the behavior of the "tablet-open" and "tablet-delete" pools.
