Subject Re: Dump and restore for AsterixDB datasets
Date Tue, 24 May 2016 22:56:56 GMT
Actually both.  We should test for binary back-compatibility but then 
have dump and restore (in serialized JSON) as a fallback so that when we 
break things, it's not hopeless for our users - they could dump 
(presumably a parallel process leaving JSON locally on each NC) and then 
restore (presumably a parallel process leading to "new binary" on each NC).
