Pushkar Raste commented on SOLR-9506:
-------------------------------------

Updated patch, added a scenario in {{PeerSyncTest}} about replica missing an update.
Looks like with don't need to remove live docs check {{if (liveDocs != null && !liveDocs.get(doc))
continue;}}

> The IndexFingerprint is cached per index searcher. it is quite useless during high throughput
indexing. If the fingerprint is cached per segment it will make it vastly more efficient to
compute the fingerprint
