Percona Server for MongoDB is an enhanced, open-source, fully compatible, highly scalable, zero-maintenance downtime database supporting the MongoDB v3.2 protocol and drivers. It extends MongoDB with MongoRocks, Percona Memory Engine, and PerconaFT storage engine, as well as enterprise-grade features like External Authentication, Audit Logging, Profiling Rate Limiting, and Hot Backup at no extra cost. Percona Server for MongoDB requires no changes to MongoDB applications or code.
NOTE: We deprecated the PerconaFT storage engine. It will not be available in future releases.
This release is based on MongoDB 3.2.13 and includes the following additional changes:
#PSMDB-127: Fixed cleanup of deleted documents and indexes for MongoRocks. When you upgrade to this release, deferred compaction may occur and cause database size to decrease significantly.
#PSMDB-133: Added the wiredTigerCheckpointSizeMB variable, set to 1000 in the configuration template for WiredTiger. Valid values are 32 to 2048 (2GB), with the latter being default.
[*]#PSMDB-138: Implemented SERVER-23418 for MongoRocks.
Percona Server for MongoDB 3.2.13-3.3 release notes are available in the official documentation.
