One parent table, having 100 child tables.
In this scenario we observed that delete and update are taking more memory
for preparing a plan
If the system under peak i am getting out of memory issue.
i.e
Select on parent table is using memory - 331456 in message context
Delete on parent table is using memory - 3746432 in message context
Delete on single child table is using memory - 8800 in message context
Select on single child table is using memory - 9328 in message context
For 250 child tables
Select on parent table is using memory - 810864 in message context
Delete on parent table is using memory - 21273088 in message context
I had seen the plans for both delete & select on parent table almost same.
why this much of memory increase in message context for delete and update
operation.
