Percona Server for MongoDB 3.2.8-2.0 is now availableAlexey Zhebel
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.
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.
--auditDestinationcan now be set to
--auditFormatcan now be set to
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
--rocksdbCompressionoption when running PSMDB with the MongoRocks storage engine. For example:
Shell1./mongod --dbpath=./data --storageEngine=rocksdb --rocksdbCompression=lz4
For a high-compression variant of LZ4:
Shell1./mongod --dbpath=./data --storageEngine=rocksdb --rocksdbCompression=lz4hc
If you want to configure this permanently, set the following parameters in the
/etc/mongod.conffile:Shell1234storage:engine: rocksdbrocksdb:compression: lz4
The release notes are available in the official documentation.
