Installing Percona Server for MongoDB

Percona Server for MongoDB 5.0.9-8 is an enhanced, source available, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 5.0.9 Community Edition. It supports MongoDB 5.0.9 protocols and drivers.

Release Highlights

  • Support of multiple KMIP servers adds failover to your data-at-rest encryption setup.

  • Allow users to set KMIP client certificate password through a flag to simplify the migration from MongoDB Enterprise to Percona Server for MongoDB.

  • Percona Server for MongoDB is now available on Ubuntu 22.04 (Jammy Jellyfish).

  • Improvements to initial syncs from a secondary sync source.

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

  • SERVER-65137 - Detect namespace changes when refreshing Collection after yielding to maintain data consistency and avoid stale catalogs.

  • SERVER-64822 - Fixed the issue with releasing the critical state too early when sharding an empty collection. This could result in unwanted writes to that collection.

  • WT-9096 - Fixed the wrong key/value returning during search near when the key doesn’t exist

  • SERVER-66041 - Prevented shard imbalances due to chunk cloner disregarding oversized chunks that contain only 1 oversized document
