Subj: | | Re: Concurrent Loads/Deletes for Staging Table |

From: | | Victor Sokovin |
| The deletes are performed with BTEQ scripts (no MLOAD). We do not have any secondary indexes on the Master table at this
time. | |
Thanks for the details. I think they confirm that deletes are using full table scan of the master table. Assuming the table is very
large, TD goes for the table lock to prevent performance problems. I would experiment with the PI defined as (country_cd, customer_nbr,
material_nbr).

Pleasure. Please keep us posted on the progress. 30 country shops are rare and such feedback is very useful.
