This document includes the new features, enhancements and fixed issues for Hazelcast IMDG v3.12.3, Open Source edition release.

Enhancements

  • Added a new implementation of SecondsBasedEntryTaskScheduler for the FOR_EACH mode to improve the performance of TransactionContext.commit(). #15586

  • Improved the client graceful shutdown mechanism so that its tasks are executed before marking a client as inactive. #15565

  • Added sent/received bytes logs for each ProtocolType into the diagnostics. #15541

  • Improved the performance of TransactionLog.add() by avoiding the LinkedList.remove() call. #15435

  • To be shown on Management Center, the clients now send both its IP address and canonical hostname. Before, only the hostname of the client was shown. #15421

  • Added the support for nested JSON objects in the arrays. #15368

Fixes

  • Fixed an issue where the node.isMaster() method could cause inconsistent behaviors when it is executed during a partition service lock. #15618

  • Fixed an issue where Management Center was not able to see the 3.12.2 members (members with CP subsystem enabled) after performing a rolling upgrade from Hazelcast IMDG 3.11.4 to 3.12.2. 'ManagementCenterService' was shutting down and throwing an exception when a CP-subsystem-enabled member was trying to report to Management Center for the first time. [#15609]

  • Made PagingPredicate a VisitablePredicate so the optimizer is able to visit its inner predicate to optimize it or to select an index to evaluate the inner predicate with. #15602

  • Fixed an issue where CP subsystem restarts were not being canceled or waited the running/scheduled discovery tasks. Otherwise, two different discovery tasks could overlap and run concurrently or one of the discovery tasks could run in a corrupted state. #15568

  • Fixed an issue where the cleaner task for expired records was logging the exceptions during migrations: the log level for PartitionMigratingException has been set to FINEST. #15543

  • Fixed an issue where the executor service message task was blocking the partition thread. #15526

  • Fixed an issue where normalFramesRead and priorityFramesRead were never incremented as seen in the diagnostic logs. #15479

  • Fixed an issue where the readBackupData and statisticsEnabled options were not respected when a new map configuration is dynamically added from a client to a running Hazelcast cluster. #15392

  • Fixed an issue where a lock was required when registering metrics on the happy path. #15378

  • Fixed an issue where some updates to the entries got lost from the write behind queue: It was a concurrency issue when there are updates to CoalescedWriteBehindQueue while StoreWorker is running. #15060
