Matteo Bertozzi commented on HBASE-14843:
-----------------------------------------
as I said, the current code load() is sync. so you need to wait every log to be
read. but that just because I didn't have time to finish that code.
but we don't need to read all the logs to be able to start procedures. think
about this case:
procedure-1 is on wal1, then we roll, procedure 2 is on wal2. both procedure
can be start before reading the other wal, and we know already that when we
read the log.
the code on the read side is almost there but there are other things in the wal
and executor that needs to be done. See

> TestWALProcedureStore.testLoad is flakey
