Hello , I'm using NIFI 1.4.0 with Mongodb 3.2.17.
Is it possible to use a composite key for "Update Query key" parameter with PutMongo processor ? My collection "primary key" is a composite key of 2 columns, SIREN & NIC, (I'm using a composite unique index to ensure uniqueness) I want to be able to make upsert operations on that collection with Nifi. Thanks for your help Regards Thomas DENIMAL
