Vrushali C commented on YARN-4062:
----------------------------------

Note: filed jira YARN-4561 for adding in enhancements like ability to turn on/off compaction
at runtime, allowing for certain whitelisting as well as blacklisting of records to be processed,
etc.

> As part of YARN-3901, coprocessor and scanner is being added for storing into the flow_run
table. It also needs a flush & compaction processing in the coprocessor and perhaps a
new scanner to deal with the data during flushing and compaction stages.
