Lars Hofhansl commented on PHOENIX-15:
--------------------------------------
For this, can't we make our own syntax? Something "FLUSH <table>"?
It's not really tied to a session but to a table. For ALTER SESSION FLUSH we
would have to keep track of exactly what tables were modified in the session
since the last time we flushed.
Alternatively we could enforce that {{ALTER TABLE <t> SET disableWAL = false}}
automatically flushes the table, since this is the really the only point in
Phoenix where one would actually want to flush a table's memstores to disk.

> I.e. one could do a "bulk load" without writing to the WAL, following by a
> memstore flush in order to guarantee the data is on disk.
> [~giacomotay...@gmail.com] suggested: ALTER SESSION FLUSH. And somehow we'd
> need to indicate which table to flush.
> This probably needs a bit more discussion.
