Ishan Chattopadhyaya commented on SOLR-8586:
--------------------------------------------
Just want to understand that those updates (at a replica) which are rejected
due to reordering, or older versions which have since been updated, would also
be counted towards this hash, isn't it?
Or, instead, would the fingerprint be the sum of hashes of only the latest
versions of all docs?

> 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?)
