Yonik Seeley commented on SOLR-8586:
------------------------------------
bq. I wonder if adding hashes of the version might be prone to problems if the
version of any given document tends to be identical to many other documents
Nope, versions are unique to a shard (the leader assigns a unique version to
every update).
> Implement hash over all documents to check for shard synchronization

> 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?)
