Jean-Daniel Cryans updated HBASE-1899:
--------------------------------------
Attachment: HBASE-1899.patch
Patch that sets the caching at 10. I thought about leaving the user set the
value but after some testing it didn't seem to change the speed much and it was
more cumbersome to use.
> Use scanner caching in shell count

> Since the shell count now uses the FirstKeyOnlyFilter, it's safe to combine
> it with scanner caching for huge count speedups.
