Installing Percona Server for MongoDB

Percona announces the GA release of Percona Server for MongoDB 4.0.6-3 on February 28, 2019. Download the latest version from the Percona website or the Percona software repositories.

Percona Server for MongoDB is an enhanced, open source, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 4.0 Community Edition. It supports MongoDB 4.0 protocols and drivers.

Percona Server for MongoDB extends the functionality of the MongoDB 4.0 Community Edition by including the Percona Memory Engine storage engine, encrypted WiredTiger storage engine, audit logging, External LDAP Authentication with SASL, hot backups, and enhanced query profiling. Percona Server for MongoDB requires no changes to MongoDB applications or code.

Release 4.0.6-3 extends the buildInfo command with the psmdbVersion key to report the version of Percona Server for MongoDB. If this key exists then Percona Server for MongoDB is installed on the server. This key is not available from MongoDB.

This release includes all features of MongoDB 4.0 Community Edition 4.0. Most notable among these are:

• Multi-Document ACID transactions

• Type conversion through the new aggregation operators

• Enhancements to the Change Streams support

Note that the MMAPv1 storage engine is deprecated in MongoDB 4.0 Community Edition 4.0.

Improvements

• PSMDB-216: The database command buildInfo provides the psmdbVersion key to report the version of Percona Server for MongoDB. If this key exists then Percona Server for MongoDB is installed on the server. This key is not available from MongoDB.
