Yonik Seeley updated SOLR-8691:
-------------------------------
Attachment: SOLR-8691.patch
Here's the patch for caching... adds an internal
SolrIndexSearcher.getIndexFingerprint() as well as a simple sync lock so
multiple threads aren't calculating it at the same time.

> When there are a high number of replicas, there may be many PeerSync calls
> (with fingerprinting). We can cache the current fingerprint with the current
> SolrIndexSearcher so it can be reused if the index hasn't changed.
