Good afternoon. I am running Apache NiFi 0.7.x. This morning I ran a large body of content through my workflow, and my content repo usage as reported by 'df -kh' spiked from less than one gigabyte of used capacity to 40G.
My files fully processed without error. My processors and queues now show 0 bytes across the board, including all processor groups. My content repository is still showing 22G usage. My expectation was that it would reduce back down to minimal capacity usage when my workflow completed processing all these files, but it has not. I run nifi on my Linux box as a service. I gracefully stopped the service. Let it sit for a minute or two. Checked my logs. No problems noted. I started nifi again as a service. No errors in the logs. I still find that the content repo disk device shows 22G used capacity. Does the content repository retain content history for a period of time after a flowfile has exited from nifi? Can that be regulated? Thanks in advance for your insights. Jim
