Percona Distribution for MongoDB 6.0.24 (2025-06-12)

Upgrade now

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 the production release of Percona Server for MongoDB 6.0.24-19 and Percona Backup for MongoDB 2.9.1.

Release Highlights

Packaging changes

Regular builds of Percona Distribution for MongoDB 6.0.24-19 are no longer supported on Ubuntu 20.04 (Focal Fossa) as this operating system has reached end of life. However, if for some reason you’re not yet able to upgrade to a newer Ubuntu OS and you’d like to still upgrade your Percona Distribution for MongoDB, contact us - we’re here to make your databases run better!

Upstream Improvements

Improvements and bug fixes, provided by MongoDB and included in Percona Distribution for MongoDB are the following:

  • SERVER-93120 - Fixed the issue with blocking Full Time Diagnostic Data Capture (FTDC) collection when checking the state of the bacupCursor by using atomic mode instead of a lock
  • SERVER-82037 - Fixed the issue with exceeding the amount of memory allocated for index creation by limiting the number of file iterators a sorter can create
  • SERVER-88400 - Fixed the issue with the shardedDataDistribution aggregation stage returning null value for timeseries when executed against bucket collections by computing metrics based on timeseries.bucketCount and timeseries.avgBucketSize
  • SERVER-92806 - Tracked nested paths through MatchExpression trees while encoding indexability for plan cache entries
  • SERVER-95976 - Introduced the “matchCollectionUUIDForUpdateLookup” parameter to enforce updateLookup to only return a document from the correct collection in the changestream stage
  • WT-13283 - Fixed the bug where WiredTiger “cache aggressive mode” for better cache usage showed the “garbage values” by applying the compare-and-swap operation to the code to avoid the value dropping to -1(which is int_max as evict_aggressive_score is an unsigned int)
