Anoop Sam John commented on HBASE-6942:
---------------------------------------
Yes Lars I am adding the logic to count the rows deleted as this way.. But I
was not able to test this.. Because getting a Status code of FAILURE or
SANITY_FAILURE seems not possible in this case... Any way better the code be
in correct shape... This is the apt way to know...
Regarding Jerry's comment - His use case seems different than ours.. Ours is a
range based row deletes.. Not even condition based. But I expect some one can
have condition based delete also.. Any way we give Scan so it is possible.. I
am specifically mentioning that this is used for deleting the entire row...
We can have separate jira issues to deal with CF deletes, column deletes,
version deletes etc... agree Lars? I will be happy to work with that.. Also
will give a trunk version once 94 based version is fine for commit.
This delete performance is being discussed in different user mail threads I
guess.. SO this kind of a example Endpoint impl will help folks...
