@mburgess Helpful information shared. I am using Nifi 1.7.1 For my case, the incremental fetching does not seem to work correctly. All records gets ingested from the database but do not make it all the way to the destination. Processor used is GenerateTableFetch then Execute SQL and the other corresponding processors down the data processing flow. Record id is captured correctly on the GenerateTableFetch property state and its up to date as the record id from the  source (db). However, it will still miss some records when processing the files making the number of records on the destination out of sync with the source from the db. Am i missing something, Would scheduling times for fetching help and how can I do that? ... View more
