> cas-catalog allows for metadata ingest transactions to spread across multiple
> catalogs such that metadata for a given transaction can end up in one or more
> catalogs. This requires a lot of memory heap space when querying on such
> types on ingests when results must be sorted and paged (because all the
> transactionIds and transactionDates must be loaded for all results so they
> can be sorted, then the give page is found and returned) . . . if you know
> you have configured your dictionaries such that "spread" ingest will never
> occur, this patch will allow you to configure cas-catalog to optimize it
> queries by not sorting the results across multiple catalog response.
