------------------------------------------------------------
bq. TezEventUpdaterTransition - we could accumulate events and then write them
upon finish once - any downsides to that?
The only concern is memory consumption. But after second thought, we will
always keep the TezEvents in memory for downstream consumption, so I think
accumulating them should be OK.
bq. Can we check that the post recovery value of various times like
startTime/launchTime/finishTime etc. remain at their pre recovery values?
I plan to add more tests to verify the new state machine transition for
recovery. Will put the time checking in these unit tests.
