Commands comparision between Document layer foundationDB versus Mongodb

I was doing some command comparision and see not all comands of Mongo works in Document layer FoundationDB like getIndexes- inorder to get list of Indexes runCommand(listIndexes) work, create compound Secondary index with mixed order , CReate User does not work ( found out No Authentication in foundation db ) - Is anyone know how user gets authenticated in FoundationDB.
Is anyone have tested list of the commands that does not work in document layer foundationDB ?


Yeah, Document Layer started with a subset of MongoDB commands. Mostly limited to CRUD operations and value indexes. More details about feature parity are given here. We welcome contributions from the community on features.

getIndex() should be relatively easy to add.

Thanks , will let you know what we need .
