Percona Distribution for MongoDB 4.4.14-14

On May 25, 2022, we released Percona Distribution for MongoDB 4.4.14-14, a freely available MongoDB database alternative, giving you a single solution that combines enterprise components from the open source community, designed and tested to work together. The aim of Percona Distribution for MongoDB is to enable you to run and operate your MongoDB efficiently with the data being consistently backed up.

This release of Percona Distribution for MongoDB includes improvements and bug fixes, provided by MongoDB and included in Percona Server for MongoDB. The most notable of them are the following:

• Support of 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.
• Fixed the issue where having a large number of split points causes the chunk splitter to not function correctly and huge chunks would not be split without manual intervention. This can be caused when having small shard key ranges and a very high number of documents and where more than 8192 split points would be needed.
• Added the repairShardedCollectionChunksHistory command to restore history fields for some chunks. This aims to fix broken snapshot reads and distributed transactions.
• Fixed incorrect logging of queryHash/planCacheKey for operations that share the same $lookup shape
• Added a new startup parameter that skips verifying the table logging settings on restarting as a replica set node from the standalone mode during the restore. This speeds up the restore process.

Percona XtraDB Cluster 5.7.37-31.57

The following lists a number of the notable updates and fixes for MySQL 5.7.37, provided by Oracle, and included in Percona Server for MySQL:

• The performance on debug builds has been improved by optimizing the buf_validate() function in the InnoDB sources.
• Fix for when a query using an index that differs from the primary key of the partitioned table results in excessive CPU load.
• Enabling PAD_CHAR_TO_FULL_LENGTH SQL mode on a replica server added trailing spaces to a replication channel’s name in the replication metadata repository tables. Attempts to identify the channel using the padded name caused errors. The SQL mode is disabled when reading from those tables.
