This is acceptable for a wide range of apps.  EtherPad, for example (which used MySQL) only flushed every second or two.  If the database crashed, then yes, you&#x27;d lose the last couple keystrokes, but that was so extremely rare it didn&#x27;t even register as a factor in the overall UX.<p>Edit: Also, you probably have bigger problems if your database goes down or your cluster falls off the map somehow.
