Percona Server for MongoDB 3.2.8-2.0 is now available

Percona announces the release of Percona Server for MongoDB 3.2.8-2.0 on August 11, 2016. Download the latest version from the Percona web site or the Percona Software Repositories.

Percona Server for MongoDB 3.2.8-2.0 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 and audit logging 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 3.2.8, and includes the following additional changes:

• Introducing the new Percona Memory Engine, which is based on a special configuration of WiredTiger that stores data in memory instead of the disk.
• --auditDestination can now be set to file, syslog, or console.
• --auditFormat can now be set to JSON or BSON.

  Note

  For more information, see Audit Logging.

• The MongoRocks engine now supports LZ4 compression. This is an upstream feature of MongoRocks contributed by Percona.To enable it, use the --rocksdbCompression option when running PSMDB with the MongoRocks storage engine. For example:
  
  ./mongod --dbpath=./data --storageEngine=rocksdb --rocksdbCompression=lz4

  1	./mongod --dbpath=./data --storageEngine=rocksdb --rocksdbCompression=lz4

  
  For a high-compression variant of LZ4:
  
  ./mongod --dbpath=./data --storageEngine=rocksdb --rocksdbCompression=lz4hc

  1	./mongod --dbpath=./data --storageEngine=rocksdb --rocksdbCompression=lz4hc

  Note

  If you want to configure this permanently, set the following parameters in the /etc/mongod.conf file:

  storage: engine: rocksdb rocksdb: compression: lz4

  1 2 3 4

  storage:   engine: rocksdb   rocksdb:     compression: lz4

The release notes are available in the official documentation.
