Pushkar Raste commented on SOLR-9506:
-------------------------------------
I computed hash w/o regard to deleted docs and cached it. All the tests are
passing even without doing steps #2 and #3. I also verified that index
fingerprint computed on entire index matches to that of fingerprint computed on
from individual segments (even after deletions).
> cache IndexFingerprint for each segment

> 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
