As a user of ETL (informatica and KETTLE) I am building a POC using NIFI to perform some of the ETL tasks that we do. KETTLE has a simple Lookup step that will directly query a database with a given key and then return values. Nifi 1.5.0 has lookups for may things like Mongo but not relational. Most answers from GOOG searches don't capture this task. Any plans for this? Having this facility will make NIFI a more more acceptable ETL replacement!
