Optimize performance of ResultList
----------------------------------
Key: PIVOT-617
URL: https://issues.apache.org/jira/browse/PIVOT-617
Project: Pivot
Issue Type: Improvement
Components: wtk
Reporter: Greg Brown
Assignee: Greg Brown
Fix For: 1.5.2, 2.0
On at least one JDBC driver, returning a 10,000-row result set using ResultList
typically takes 75-85s, whereas retrieving the same data using ResultSet takes
only 10s. Optimize performance of ResultList so it is on par with direct
ResultSet access.
Note that this will constitute an API change and slight loss of functionality
(ResultList's iterator will only support forward-scrolling iteration, whereas
previously it had supported bi-directional iteration). However, the performance
benefits for the common case (forward-scrolling) should far outweigh the loss.
