Hello Community! Hope you're all doing fine.   I'm beggining my Nifi studying and i'de like to replicate a process that i have running in other plataforms. My goal is to read a CSV and process it row by row to insert into a sql server table.   So far so good, i was able to do this with the following:   GetFile -> SplitRecord -> ConvertRecord (to json) -> ConvertJSONtoSQL -> UpdateAttribute (date conversion) -> PutSQL.   But i need to validade if the record already exists in the destiny table. Can anyone help me with that? Already looked for but i wasn't able to find somethig like it.   If you guys have a solution that is better and completely different, no problem, i'm open to any change.   Thanks in advance! ...
