Eugene Koifman commented on HIVE-19214:
---------------------------------------
SDPO should work, though that is orthogonal. If you have a simple Insert into
an acid table, this would likely make reads suboptimal and so requires much
more frequent compactions. This may be justified in streaming (esp w/dynamic
partitions) but it's not in all cases. For example, if you have a table that
is infrequently written to by large insert statements it may not need any
compactions at all (unless you make this change as is) . There should be some
config that can be set control this at least at table level though would be
better per statement/connection.
