    Percona Distribution for MongoDB 4.2.17 (2021-10-11)¶

    Release date October 11, 2021
    Installation Install Percona Distribution for MongoDB

    Percona Distribution for MongoDB is a collection of solutions to run and operate your MongoDB efficiently with the data being consistently backed up.

    Percona Distribution for MongoDB includes the following components:

    • Percona Server for MongoDB is a fully compatible source-available, drop-in replacement for MongoDB.

    • Percona Backup for MongoDB is a distributed, low-impact solution for achieving consistent backups of MongoDB sharded clusters and replica sets.

    This release of Percona Distribution for MongoDB is based on Percona Server for MongoDB 4.2.17-17 and Percona Backup for MongoDB 1.6.0.

    Release Highlights¶

    The bug fixes, provided by MongoDB and included in Percona Server for MongoDB 4.2.17-17 and Percona Distribution for MongoDB 4.2.17 are the following:

    • The libsasl2 dependencies are added for DEB-based operating systems to enable GSSAPI and Kerberos authentication to work out-of-the box after installing MongoDB (SERVER-54729)

    • The number of modify updates in WiredTiger is now limited to prevent performance issues (WT-7776)

    • Errors related to proxy connections receive new error codes so that they don’t change the behavior of clients’ drivers (SERVER-50549)

    • Pre-warming of connection pools in mongos tier (SERVER-44152)

    • Improvements to Secondary slowdowns or hangs (SERVER-34938)

    Percona Backup for MongoDB 1.6.0 improvements include the following:

    • Support for Percona Server for MongoDB and MongoDB Community 5.0

    • Point-in-time recovery enhancements: ability to restore from any previous snapshot and configurable span of oplog events

    • JSON output for PBM commands to simplify interfacing PBM with applications
