> A recent issue found at a customer unveils a potential issue with the async indexer. Reading the AsyncIndexUpdate.updateIndex it looks like it is doing the entire update of the async indexer *in one go*, ie in one commit.
> When there is - for some reason - however, a huge diff that the async indexer has to process, the 'one big commit' can become gigantic. There is no limit to the size of the commit in fact.
> So the suggestion is to do intermediate commits while the async indexer is going on. The reason this is acceptable is the fact that by doing async indexing, that index is anyway not 100% up-to-date - so it would not make much of a difference if it would commit after every 100 or 1000 changes either.
