Installation

Installing Percona Server for MongoDB

Percona Server for MongoDB 4.4.14-14 is an enhanced, source-available, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 4.4.14 Community Edition. It supports MongoDB 4.4.14 protocols and drivers.

Release Highlights

Percona Server for MongoDB now supports the master key rotation for data encrypted using the Keys Management Interoperability Protocol (KMIP) protocol (tech preview feature). This improvement allows users to comply with regulatory standards for data security.

Other improvements and bug fixes introduced by MongoDB and included in Percona Server for MongoDB are the following:

  • WT-8924 - Fixed a bug that causes replication to stall on secondary replica set members in a sharded cluster handling cross-shard transactions. It is caused by WiredTger to erroneously return a write conflict when deciding if an update to a record is allowed. If MongoDB decides to retry the operation that caused the conflict in WiredTiger, it will enter an indefinite retry loop, and oplog application will stall on secondary nodes.

    If this bug is hit, the secondary nodes will experience indefinite growth in replication lag. Restart the secondary nodes to resume replication.

    This bug affects MongoDB 4.4.10 through 4.4.13 and 5.0.4 to 5.0.7.

    Update to the latest version to avoid the secondary replication stall and lag issues.

  • SERVER-60412 - Check if the host has cgroups v2 enabled and read the memory limits according to that.

  • SERVER-62229 - Fix invariant by allowing applying index build abort entry when in recoverFromOplogAsStandalone mode

  • SERVER-55429 - Fixed the issue with blocked migrations by adding a timeout to migrations when waiting for range deletions on intersecting ranges
