Hi,

I want to know more details about the Clustered Index Delete. Is that Clustered Index Delete in the execution plan is good or bad or we can neglect that cost. Is there any way to avoid that clustered Index delete operator from the execution plan.
Thanks,
Ramana

Not likely. If you are deleting data, the clustered index needs to reflect that.

A clustered index stores the data. So when you run a delete statement, it goes to the clustered index to delete the data. That's how it works.

Hi,

What I understand is

So clustered Index delete or insert means there is no sign for bad performance. Just it is showing that delete or insert operation occurred.

Please correct me if I understand wrong.

Thanks,

Nope. You got it. If you're inserting to a table with a clustered index, it's inserting into the clustered index. That event, by itself, is absolutely not a performance problem.
