Currently a CTE is always being resolved by going back to disk. For example, if the same CTE is reused with in the same query, for each time it is used, it is reading from the disk and processing the entire query. So if it is used 5 times with in the query, it will read same tables 5 times and process the entire query 5 times.
I would like to make IDAA reuse the resultset created after the first execution so that it will avoid multiple disk reads as well as the re-evaluating the same query repeatedly.
DB2 currently reuses the resultset and I'm hoping similar functionality in IDAA.
