Percona Server for MongoDB 3.2.8-2.0¶
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.
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:
Introducing the new Percona Memory Engine, which is based on a special configuration of WiredTiger that stores data in memory instead of the disk.

--auditFormatcan now be set to
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
--rocksdbCompressionoption 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
If you want to configure this permanently, set the following parameters in the
storage: engine: rocksdb rocksdb: compression: lz4
