| Subj: | | Production Join with No Confidence (Need Alternate) |
| |
| From: | | Vikram Singh |
Hi
Can someone help me finding the alternate for this bottleneck or it is bottleneck or not:
| | | | |
| | ) | We do an all-AMPs JOIN step from Spool 2 (Last Use) by way of an all-rows scan, which is joined to Spool 3 (Last Use). Spool 2 and Spool 3
are joined using a product join, with a join condition of ("(WEEK_CODE >= BEGIN_WEEK_CODE) AND (WEEK_ID < END_WEEK_CODE)"). The result goes into
Spool 1 (group_amps), which is built locally on the AMPs. The size of Spool 1 is estimated with no confidence to be 7,665,540 rows. The
estimated time for this step is 3 minutes and 9 seconds.
