Percona Server for MongoDB 5.0.4-3 (Release Candidate)


December 8, 2021


Installing Percona Server for MongoDB

Percona Server for MongoDB 5.0.4-3 is an enhanced, source-available, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 5.0.4 Community Edition.

It is rebased on MongoDB 5.0.4 Community Edition and supports MongoDB 5.0.4 protocols and drivers.


Due to many core changes to WiredTiger and the core server introduced to facilitate new features such as resharding, time series collections, and API versioning, MongoDB 5.0.x is still unstable. We do not recommend using this release candidate for production environments.

Release Highlights

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

  • Fixed delays in establishing egress connections on mongos due to delayed responses from

  • Allowed replication state changes to interrupt lock acquisition. This interruption fixes deadlocks that may occur when a primary node steps down with profiling enabled.
