Percona Distribution for MongoDB 4.4.12

On February 7, 2022, we released Percona Distribution for MongoDB 4.4.12. It 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. This release includes improvements and bug fixes provided by MongoDB and included in Percona Server for MongoDB. The most notable from them are the following:

• Defined a timeout for a health check process and throw an error when the process fails to complete within a timeout. This prevents health check to hang.
• Added the ability to transition through the valid states of the fault manager, and the interface to observer and log its state transitions.
• Fixed broken OP_QUERY exhaust cursor implementation
• Added the repairShardedCollectionChunksHistory command to restore history fields for some chunks. This aims to fix broken snapshot reads and distributed transactions.

Percona Distribution for MongoDB 5.0.6

Percona Distribution for MongoDB 5.0.6 was released on February 10, 2022. It is based on Percona Server for MongoDB 5.0.6-5 and Percona Backup for MongoDB 1.6.1 and includes bug fixes provided by MongoDB and included in Percona Server for MongoDB. The most notable from them are the following:

• Fixed an issue with inconsistent data observed during the direct upgrade from 4.4.3 and 4.4.4 to 4.4.8+ and 5.0.2+. Data inconsistency was caused by the incorrect checkpoint metadata to sometimes be recorded by MongoDB versions 4.4.3 and 4.4.4. WiredTiger used this metadata during node startup that could lead to data corruption and could cause the DuplicateKey error. The fix requires the upgrade to versions 4.4.11+ or 5.0.5+. For details, refer to WT-8395.
• Fixed issue unavailability of a shard in sharded clusters. Affects MongoDB versions 5.0.0 – 5.0.5.
• Fixed time-series bucket OID collisions by adding the difference between the actual timestamp and the rounded timestamp to the instance portion of the OID.
