Percona Server for MongoDB 6.0.9-7 (2023-09-14)


Percona Server for MongoDB 6.0.9-7 is an enhanced, source-available, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 6.0.9 Community Edition.

It is based on MongoDB 6.0.9 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
