Major Description
Currently, since OAK-980 (and OAK-1246), the asynchronous indexer makes two commits per invocation regardless of whether there are any changes to the indexed content. This can be a bit confusing and in some cases even troublesome especially in a mostly read-only deployments where the frequent extra commits just add unnecessary noise.
It would be better if the async indexer only made commits when there actually are content changes to be indexed.
