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 authentication, hot backups, and enhanced query profiling.
