Percona Server for MongoDB 4.2.20-20 (2022-05-23)¶
May 23, 2022
Percona Server for MongoDB 4.2.20-20 is an enhanced, source-available, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 4.2.20 Community Edition. It supports MongoDB 4.2.20 protocols and drivers.
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:
SERVER-64983 - Abort the WiredTiger transaction after releasing Client lock to avoid deadlocks
SERVER-60412 - Check if the host has
cgroupsv2 enabled and read the memory limits according to that.
SERVER-64642 - Return the shutdown error as the top level error when batch writing command fails due to mongos shutdown.
SERVER-59435 - Fixed the double free state for the
DocumentSource::optimizeAt()pipeline by making sure all pointers are in place before disposing the pipeline prefix
