Sangjin Lee commented on YARN-4074:
-----------------------------------
That's correct. In other words, those are used to do {{getEntity()}}. That's
why I said "a reader for *single-entity reads*" (plural "reads"), as opposed to
"a reader for a single entity read".
> [timeline reader] implement support for querying for flows and flow runs
