Percona Distribution for MongoDB 4.4.27 (2024-01-17)

Installation

Percona Distribution for MongoDB is 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.

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 4.4.27-26 and Percona Backup for MongoDB 2.3.1.

Release Highlights

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

  • Handled missing index idents during standalone startup recovery after unclean shutdown.

  • Improved the startupRecoveryForRestore behavior by allowing writes in read-only mode from ident reaper
  • Fixed the issue with the balancer hitting an invariant during balancer round
  • Fixed the rollback-to-stable behavior to read the newest transaction value only when it exists in the checkpoint.

  • Support for Percona Server for MongoDB 7.0.x
  • The ability to define custom endpoints when using Microsoft Azure Blob Storage for backups
