Shalin Shekhar Mangar commented on SOLR-6820:
---------------------------------------------
Shouldn't we increase the default numBuckets to 65536? It doesn't look very
expensive to do so -- the numBuckets are used to create an array of
VersionBucket objects each of which contains a single long value. The benefit
is quite significant for such a small cost.
> The sync on the VersionInfo bucket in DistributedUpdateProcesser#addDocument
> appears to be a large bottleneck when using replication.
