How about my original suggestion which is: tables that sacrifice
crash-safety for speed... or much faster tables at the expense of
crash-safety?  A sub-note to that could be that in the unlikely event
of a crash, the table data will be lost, but not the table.

I personally haven't used "in-memory" tables, so may be appropriate to
the DBA demographic.  It doesn't sound right in my head though.
