Percona Distribution for MongoDB 7.0.18 (2025-04-24)

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. Its aim 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 7.0.18-11 and Percona Backup for MongoDB 2.9.1.

Release Highlights

Improved compatibility of Percona Server for MongoDB with MongoDB Enterprise Advanced for data-at-rest encryption using KMIP

We have added the security.kmip.useLegacyProtocol configuration option to improve compatibility of Percona Server for MongoDB with MongoDB Enterprise Advanced. Now you can migrate from MongoDB Enterprise Advanced to Percona Server for MongoDB without having to modify the configuration file. Since Percona Server for MongoDB uses KMIP protocol version 1.0 by default, it ignores this option and prints the log message about it.

Audit log improvements

Enjoy a better user experience with these improvements to audit logging:

  • You can output logging information either to a syslog, a file or to print in the console. Now Percona Server for MongoDB correctly parses the specified destination and creates a logging file only if you explicitly defined the file as its value. This helps keep the system clean from unnecessary files

  • By default, Percona Server for MongoDB saves the log file at the server’s configured log path or to a directory from where mongod was started if the server’s log path is undefined. You can also set a custom path to output a log file. For both cases, Percona Server for MongoDB checks if the audit log file can be opened for writing to ensure that logging information is written and available.

Compatibility with Amazon Linux 2023

We build and test Percona Distribution for MongoDB only on the latest versions of Amazon Linux 2023. Because of the way Amazon Linux updates their libraries, Percona Distribution for MongoDB 7.0.18 is compatible only with Amazon Linux 2023.7.x and won’t work on Amazon Linux 2023.6.x and older.

To upgrade to 7.0.18, make sure that you run Amazon Linux 2023.7.x. Use the update instructions

Upstream Improvements

  • Fixed the issue with timeseries filtering missing extended-range events when sharded by generating timeseries _id comparisons only on mongod nodes
  • Improved logging behavior for roles not being mapped to users to throw a warning for internally-authorized users and to show this message with higher log verbosity level for externally-authorized users so that this message can be suppressed
  • Extended logs for a thread is interrupted by replica set stage change with details like thread name and the reason for its interruption
  • Added enumeration to track the cleanup state for $out stage to properly drop buckets collection during interrupt
  • Prevented CollectionRoutingInfoTargeter from iterating all chunk ranges during update and delete to improve performance
  • Added redaction of the BSON command for “Plan executor error” warning logs to prevent the entire command text (possibly including PII) to end up in the logs
  • Reduced the strictness of an invariant check for the unique ID (uid) in the session identifier (lsid) to match between the operation’s context (opCtx) and the incoming command request by treating it as a code error, logging it and have the server continue operating

Percona Backup for MongoDB 2.9.1 improvements:

  • Fixed the issue that prevented PBM from taking physical backups in deployments using both MongoDB Community and Percona Server for MongoDB.
