Re: coprocessor enabled put very slow, help please~~~
Is your CheckAndPut involving a local or remote READ? Due to the nature of
LSM, read is much slower compared to a write...

Subject:        coprocessor enabled put very slow, help please~~~

hi,
   i am trying to insert few million documents to hbase with mapreduce. To
enable quick search of docs i want to have some indexes, so i tried to use
the coprocessors, but they are slowing down my inserts. Arent the
coprocessors not supposed to increase the latency?
my settings:
    3 region servers
   60 maps
each map inserts to doc table.(checkAndPut)
regionobserver coprocessor does a postCheckAndPut and inserts some rows to
a index table.
Sincerely,
Prakash
