Subj:   Re: Tpump load challenges
 
From:   Robert Meunier

Brian,

A reason the DELETE might be applying a table lock is because you are not providing all the columns in the Primary Index in the WHERE clause. Unless of course you are using a MultiLoad to do the DELETE which always applies a table lock. Could you possibly provide the rest of the columns? The DELETE would then do Row locks.

I don't know anything about how you are processing all the stores individually, but would it be possible to delete all the individual stores data in one process instead of each one individually? It would limit you lock contention to one process, but if it was a MultiLoad DELETE it would probably be pretty quick.
