Percona Server for MongoDB 3.2.8-2.0

Percona is glad to announce the release of Percona Server for MongoDB 3.2.8-2.0 on August 11, 2016 Downloads are available here and from the Percona Software Repositories.

Percona Server for MongoDB is a 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 engines, as well as several enterprise features. Percona Server for MongoDB requires no changes to MongoDB applications or code.

Note

The PerconaFT storage engine has been deprecated and will not be available in future releases.

This release is based on MongoDB 3.2.8, and includes the following additional changes:

New Features

  • 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 Auditing.

  • 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 Percona Server for MongoDB with the MongoRocks storage engine. For example:

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

    For a high-compression variant of LZ4:

    ./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
