Percona Server for MongoDB is an enhanced, open source, fully compatible, highly scalable, zero-maintenance downtime database supporting the MongoDB v3.6 protocol and drivers. It extends MongoDB with Percona Memory Engine and MongoRocks storage engine, as well as adding features like external authentication, audit logging, and profiling rate limiting. Percona Server for MongoDB requires no changes to MongoDB applications or code.
This beta release is based on MongoDB 3.6.1 and includes the following additional changes:
- MongoRocks is based on RocksDB 5.7.3.
- #PSMDB-184 – MongoRocks reindexing collection or repairing database commands can cause inconsistency when doing immediate majority read in a replica set.
- #PSMDB-185 – MongoDB has its own notion of time, including an expected commit order for transactions that may be inconsistent with the order assigned by MongoRocks. This can cause majority read inconsistencies in highly concurrent environments in replica set mode.
Percona Server for MongoDB 3.6.0-1.0beta release notes are available in the official documentation.
