    Percona Server for MongoDB 4.2.19-19 (2022-03-29)¶

    Release date March 29, 2022
    Installation Installing Percona Server for MongoDB

    Percona Server for MongoDB 4.2.19-19 is an enhanced, source-available, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 4.2.19 Community Edition. It supports MongoDB 4.2.19-19 protocols and drivers.

    Release Highlights¶

    Percona Server for MongoDB now supports Keys Management Interoperability Protocol (KMIP) so that users can store encryption keys in their favorite KMIP-compatible key manager to set up encryption at rest. This is a tech preview feature.

    The list of bug fixes introduced by MongoDB and included in Percona Server for MongoDB is the following:

    • SERVER-62065 - Added the repairShardedCollectionChunksHistory command to restore history fields for some chunks. This aims to fix broken snapshot reads and distributed transactions.

    • SERVER-60685 - Fixed an issue with transaction coordinator crashing if the transaction is aborted when attempting to commit a transaction.

    • SERVER-60682 - Fixed the issue with the distributed transactions being in the prolonged prepared state that was caused by the blocking of acquiring the WiredTiger write tickets by the transaction coordinator.

    • SERVER-40691 - Fixed an issue with an empty array for the $nin statement.

    New Features¶

    • PSMDB-971: Added support for KMIP encryption. Now users can store encryption keys in their favorite KMIP-compatible key manager to set up encryption at rest.

    Bugs Fixed¶

    • PSMDB-957: Fixed server crash caused by LDAP misconfiguration. Now the server logs an error message and exits.

    • PSMDB-950: Fix LDAP authentication using mongo CLI failure for Percona Server for MongoDB installed from tarball
