Percona Server for MongoDB 6.0.5-4 (2023-03-29)

Release date March 29, 2023
Installation Installing Percona Server for MongoDB

Percona Server for MongoDB 6.0.5-4 is an enhanced, source-available, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 6.0.5 Community Edition.

It is rebased on MongoDB 6.0.5 Community edition and supports the upstream protocols and drivers.


We don’t recommend this version for production use due to the issue with routing sharding time series collections SERVER-80203 which could result in metadata inconsistency. The routing issue is observed when documents have the shard key containing the embedded object composed of multiple fields.

The issue affects time series sharded collections starting in MongoDB version 5.0.6 through versions 5.0.21, 6.0.11 and 7.0.2. It is fixed upstream in versions 5.0.22, 6.0.12 and 7.0.4 and included in Percona Server for MongoDB 5.0.22-19, 6.0.12-9 and 7.0.4-2.

If you are using time series collections, upgrade to the fixed version of MongoDB / Percona Server for MongoDB as soon as possible and follow closely the upstream recommendations outlined in SERVER-80203 for remediation steps.

Release Highlights

  • Added support for authentication using AWS IAM enables you to natively integrate Percona Server for MongoDB with AWS services, increase security of your infrastructure by setting up password-less authentication and offload your DBAs from managing different sets of secrets. This is a technical preview feature
  • Improved master key rotation for data at rest encrypted with HashiCorp Vault enables you to use the same secret key path on every server in your entire deployment thus significantly simplifying the secrets management and key rotation process.

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

  • SERVER-61909 - Fixed a hang when inserting or deleting a document with large number of index entries
  • SERVER-66469 - Fixed the issue with filtering time-series collections that contain the date values earlier than Unix epoch (1970)
  • SERVER-68122 - Fixed the issue with adding a new unencrypted node into an encrypted replica set by removing options which might not apply for this node.
  • SERVER-73232 - Changed the default log verbosity level for _killOperations to D2.
  • SERVER-73266 - Fixed deadlock that can occur during index creation
  • SERVER-73009 - Resolved the issue with the sort order on clustered collections where requested decreasing order returned returned results in increasing order
  • SERVER-72512 - Fixed the issue with indexes reported as valid while being inconsistent by improving the validation of those indexes
  • SERVER-71219 - Fixed the migration of distributed transactions by registering the migration source operation observer hook in all paths where transactions transition into the prepared state.
