[jira] [Created] (OODT-417) Refactor Paging in Lucene Catalog
Refactor Paging in Lucene Catalog
---------------------------------
Key: OODT-417
URL: https://issues.apache.org/jira/browse/OODT-417
Project: OODT
Issue Type: Improvement
Components: file manager
Affects Versions: 0.3
Reporter: Paul Ramirez
Assignee: Paul Ramirez
Priority: Minor
Fix For: 0.4
Instead of doing a skip we can just use an item from the last page to augment the query. This would allow us not to scan through a set of docs and the fist N could be used; where N = page size. We already naturally sort by "CAS.ProductReceivedTime" so the idea is just to use the last page's last item and make sure we query for items greater than that. This should speed things up especially when hitting later pages.
