    Percona Server for MongoDB 4.2.0-1 (2019-09-09)¶

    We are pleased to announce the launch of Percona Server for MongoDB 4.2.0-1 on September 9, 2019. Our engineers have been hard at work to bring this to you less than a month after the launch of MongoDB 4.2 Community Edition 4.2.

    Percona Server for MongoDB 4.2.0-1 includes all of the new features of the latest version of MongoDB 4.2 Community Edition, as well as providing our users with Enterprise-level enhancements for free.

    Download the latest version from the Percona website or the Percona software repositories.

    Percona Server for MongoDB is an enhanced, source available, and highly-scalable database that acts as a fully-compatible, drop-in replacement for MongoDB 4.2 Community Edition. It supports MongoDB 4.2 protocols and drivers.

    Percona Server for MongoDB extends the functionality of the MongoDB 4.2 Community Edition by including the Percona Memory Engine storage engine, encrypted WiredTiger storage engine, audit logging, external LDAP Authentication, hot backups, and enhanced query profiling. Percona Server for MongoDB requires no changes to MongoDB applications or code.

    Percona Server for MongoDB 4.2.0-1 includes all of the features of MongoDB 4.2 Community Edition. The most notable among these are:

    • Distributed transactions (or Multi-Document Transactions) to enable transactions on sharded clusters and replica sets removing the transaction total size limit.

    • Wildcard indexes to have indexes span sets of unknown or arbitrary fields.

    Improving its security, MongoDB 4.2 Community Edition resolves the following CVEs: CVE-2019-2389 and CVE-2019-2386.

    MongoDB 4.2 Community Edition removes the MMAPv1 storage engine along with MMAPv1 specific configuration options, parameters and commands. It also removes a number of commands and methods not related to MMAPv1.

    Percona Server for MongoDB 4.2.0-1 is based on MongoDB 4.2.0.

    There are a number of benefits in downloading the latest version of our software, including the impressive new features referenced above, which make it easier to run and manage your MongoDB database and help to keep your data safe.

    For further information on the application of these new features, you can also visit our recent blogs which dig into the pros and cons of each in detail:

    • Diving into the MongoDB 4.2 Release Small Print

    • The Long-Awaited MongoDB 4.2 GA Has Landed

    We believe that MongoDB 4.2 Community Edition is a great improvement on previous versions, with some long-awaited enhancements, including features which were previously only available in the Enterprise version.

    Percona Server for MongoDB is a free and open source drop-in for MongoDB 4.2 Community Edition and includes all of the new features of 4.2, and more! This makes it an attractive proposition for businesses looking to have a robust database software solution in place and make the most of their IT budget.
