Alexander Shorin commented on COUCHDB-1654:
-------------------------------------------
[~rnewson] , I may be wrong about, but roots of the new view engine leads to https://issues.apache.org/jira/browse/COUCHDB-1270
- there is benchmark data and his results. As for my experience, it's still a bit faster then
the old one (or may it's because of https://issues.apache.org/jira/browse/COUCHDB-1334 ?),
but without any proofs or numbers, sorry.

> view sigs and location changed between 1.2.x and 1.3.x, which would cause full rebuilds.
