It does not slow the processing. The ControlRate processor will allow data to queue in its input side and based on its configured setting only allow x number of FlowFiles through over y amount of time. lets say it is configured to let 5 KB of data through every 1 minute. If you feed it a 37 MB file, it does not transfer just pieces of that FlowFile. It will feed through the entire 37 MB FlowFile and then not allow another FlowFile through until the average data per 1 minute is 5 KB.</SPAN></P><P>&nbsp;</P><P><SPAN>Above explanation extracted from another post:&nbsp;<A href="https://community.cloudera.com/t5/Support-Questions/ControlRate-and-BackPressure-seems-not-work-for-control-the/td-p/207455" target="_blank">https://community.cloudera.com/t5/Support-Questions/ControlRate-and-BackPressure-seems-not-work-for-control-the/td-p/207455</A></SPAN></P> Mon, 22 Mar 2021 05:16:53 GMT Daming Xue 2021-03-22T05:16:53Z
