> The initial proposal for this improvement was:
> {quote}
> Change processing for listeners that are only interested in external
> events could be simplified because there is no commit info for
> external changes. The basic idea is that the node store implementation
> may be able to optimize batch processing of multiple external changes
> and does not need to process each external change individually. The
> DocumentNodeStore would use the journal to identify external changes
> and need to come up with a way to ignore overlapping local changes.
> With this new feature, expensive listeners that process local as well
> as external events could be split into two separate listeners, each
> optimized for the type of changes.
> {quote}
> Later the proposal was changed in a more general queueless change processor. See first comment.
