> With EOS enabled we don't checkpoint on {{commit}} so there is no need to call {{flush}} when committing _top level tasks_ .  However for _standby tasks_ we still checkpoint thus need to still flush when committing. We need to develop an approach where we can optimize for top level tasks by avoid flushing on commit, while still preserving flush on commit for standby tasks.
