Re: Trigger performance not good

Hi Chuck,

Thank you for your detailed response.

I'm not sure if the following would create a distinct isolation-level so
I'll ask ...

If I re-write the trigger so it does less work and write to an intermediate
table, and have a trigger on the intermediate table to do all the work of
calling the UDFs and write to the interface table, will that free up the
application making the initial updates/inserts? Or is the entire process
still considered all-in?


No, your initial app won't get control back till the trigger on the
intermediate table completes.

You can't have the work be done by triggers _anywhere_ if you want it done
asynchronously. ​
