IndexedDB: Only reset prefetch caches for cursors in same transaction
Correct prefetching is predicated on resetting the cache when other
requests come in that could invalidate it (i.e. writes) or result in
requests processing out of order (i.e. everything). When prefetching
was originally implemented, the IDB implementation only handled one
transaction at a time, so resetting was done with a big hammer - reset
all of a front-end's caches when any other request is made. This was
acknowledged as future work during code review.
The future is now! Only reset caches for cursors from the same
transaction as the triggering request, which should be a performance
win for concurrent transactions in the same front-end.
