Yonik Seeley commented on SOLR-8586:
------------------------------------
You can set the environment variable solr.disableFingerprint to "false" to
disable the fingerprint check.
If your indexes ever have updates to existing documents, then you're still
risking OOMs anyway (the first time a replica detects that an update may be
reordered will cause the FieldCache to be populated for _version_ for that
segment). The fingerprint makes that happen up-front (what I meant to say in
my previous message was "the maximum required amount of memory shouldn't be
changed").

> 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?)
