Hi Jim,
I am not advocating indexing on deleted, in fact by using the technique as described you only need the primary key to locate deleted records. It was my understanding however from benchmarking we performed that it is only when there are many repeating entries in a given key set that performance suffers. Do you have results that differ with my findings? How did you conduct the test?
