Just FYI: When I changed the wildcard deletes with exact key matches
in a loop, the performance of removing entries in this table dropped
by about 40% in my particular application.

Is there some way to remove batches of records more efficiently? Would
it make a difference to use a dirty_delete?

Thx,

Ben
