Re: How to get acceptable/repeatable performance on huge table

Unfortunately, we need really fast access to all rows with a specific Uid, thats the most important function of this table. (We do in the order of 1000 such lookups per sec and can't accept loosing performance there).

We have good peformance with that today but it would become worse with an ordinary Uid index - don't you agree?

Would not an additional index (adId, uid) do the same thing as rearranging the PK?
