Pushkar Raste updated SOLR-9310:
--------------------------------
Attachment: PeerSync_Experiment.patch
This an experimental patch, just to test what happens if PeerSync falls on its
face.
I could not think of an elegant way to test it, but it just proves that we if
compare index fingerprint only before applying updates, it would not validate
if PeerSync itself is successful.
IMHO we should know that after recovery nodes are in sync irrespective of
whether they were in sync at some point before failure or not.
> PeerSync fails on a node restart due to IndexFingerPrint mismatch

> 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.
