Pushkar Raste commented on SOLR-9310:
-------------------------------------
[~ysee...@gmail.com] and [~markrmil...@gmail.com], in
[SOLR-8690|https://issues.apache.org/jira/browse/SOLR-8690] you mentioned that
fingerprint check could have performance cost. Was performance cost you
mentioned could be due to the fact that PeerSync was failing on node restart
and hence Solr was falling back to do full replication ?
Is PeerSync failing on node restart expected behavior
> PeerSync fails on a node restart due to IndexFingerPrint mismatch

> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Pushkar Raste
> Attachments: PeerSyncReplicationTest.patch
>
>
> I found that Peer Sync fails if a node restarts and documents were indexed
> while node was down. IndexFingerPrint check fails after recovering node
> applies updates.
> This happens only when node restarts and not if node just misses updates due
> reason other than it being down.
> Please check attached patch for the test.
