Subject [jira] [Commented] (ACCUMULO-3592) Improvements to RFile
Date Thu, 19 Feb 2015 20:36:12 GMT

Christopher Tubbs commented on ACCUMULO-3592:
---------------------------------------------

If you're suggesting that this change will not require future RFile version number bumps when
we add stuff to this structure, then yeah, let's do it now. If it doesn't prevent the need
to do RFile version number bumps to track compatibility, then I don't see what an intermediate
RFile version which only changes the format of a data structure gets us, if it also doesn't
come with added functionality.

This is currently just a few writable things thrown together -- it would be nice to convert
this into some pb/thrift message that we can add/remove things easily.
