    Percona Distribution for MongoDB 5.0.5 (2021-12-28)¶

    Release date: December 28, 2021
    Installation: Installing Percona Distribution for MongoDB

    Warning

    We don’t recommend this version for the production use due to the critical issue with sharding metadata inconsistency: SERVER-68511. The metadata inconsistency is observed when running the movePrimary command on the database that has the Feature Compatibility Version (FCV) set to 4.4 or earlier. Affects MongoDB versions 5.0.0 through 5.0.10 and MongoDB 6.0.0. Upgrade to the fixed version of MongoDB 5.0.11 / Percona Server for MongoDB 5.0.11-10 as soon as possible.

    Please follow closely the upstream recommendations outlined in SERVER-68511 to work around this issue and for the remediation steps, if your cluster is affected.

    We are pleased to announce the release of the Percona Distribution for MongoDB for the recent major version 5.0.x.

    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 5.0.5-4 and Percona Backup for MongoDB 1.6.1.

    Release Highlights¶

    This release of Percona Distribution for MongoDB includes bug fixes, provided by MongoDB and included in Percona Server for MongoDB. The most notable from them are the following:

    • Added histograms to track latency for tasks scheduled on the reactor thread.

    • Fixed an issue when resharding a collection that could cause data inconsistency (lost writes) due to incorrect actions by the ReshardingCoordinator and attempts to commit anyway. Also could cause fassert() to config server primary.

    • Fixed an issue with stalls on the config server. Updates to config server during resharding may wait too long for oplog slot thus stalling replication on config server indefinitely.

    • Fixed a resharding issue relating to RecipientStateMachine that caused the server to crash

    Percona Backup for MongoDB 1.6.1 improvements include the following:

    • Improved backup and point-in-time recovery routines alignment by using sequential delete-pitr/install-backup operations instead of in-memory backup intent. This fixes the inability of a backup to start.

    • Added support for automated access to S3 buckets using an EC2 instance profile. When Percona Backup for MongoDB is deployed using an EC2 instance, EC2 environment variables and metadata are used for S3 authentication, saving you from explicitly specifying S3 credentials in the Percona Backup for MongoDB configuration file. This comes handy for architectures deployed using the services like Amazon EC2, kiam, kube2iam or irsa.

    • Extended logging for pbm-agents. This improves user experience with Percona Backup for MongoDB.
