Allow for unsorted paging across all catalogs to give option of lowering heap
footprint

Key: OODT-97
URL: https://issues.apache.org/jira/browse/OODT-97
Project: OODT
Issue Type: Improvement
Components: catalog
Affects Versions: 0.1-incubating
Environment: none
Reporter: Brian Foster
Assignee: Brian Foster
Priority: Minor
Fix For: 0.2
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.
