Hello guys, I have the below NiFi flow, based on the thread https://community.hortonworks.com/questions/70562/executesql-dynamic-query.html#comment-71349 The ExecuteSQL processor is executing very simple select query which returns the results very fast if executed from command line.. I dunno why I keep getting huge queue before the executeSQL, I tried to increase the running threads but still the output is slow... any suggestion how to improve this ? bearing in mind that I have another process group which execute insert query and running smoothly, fast ? Note the queue is full before ExectueSQL, I also got heap size errors when I increased the ExecuteSQL threads to 16 ? I attached the flow as well Thanks forum ... View more
