Subject [jira] [Commented] (SOLR-8586) Implement hash over all documents to check for shard synchronization
Date Wed, 27 Jan 2016 12:48:39 GMT

Yonik Seeley commented on SOLR-8586:
------------------------------------

The latter.  We're looking at that is in the index, and that will only have the last version
of every non-deleted document.

> An order-independent hash across all of the versions in the index should suffice.  The
hash itself is pretty easy, but we need to figure out when/where to do this check (for example,
I think PeerSync is currently used in multiple contexts and this check would perhaps not be
appropriate for all PeerSync calls?)
