I know that Percona MongoDB supports MongoDB enterprise, but I wonder if there is anything else.
Hi @Kim_Hakseon the Percona Server for MongoDB uses the community code and then adds features on top of it. Take a look at the comparison of features between MongoDB Community, MongoDB Enterprise and PSMDB.
While Percona offers support for MongoDB Enterprise, PSMDB is not MongoDB Enterprise. Percona added enterprise features but they are not using MongoDB’s code for those features.
