Subject Coprocessor slow down problem!
Date Fri, 30 Nov 2012 07:43:02 GMT
Dear all,

I have two tables, named test and tracking. For every put in the test
table, I defined a postPut trigger to insert the same data into
tracking table. I tested about 50 thousands tuples. The strange thing
for me is for the first 20 thousands tuples, the speed is very fast (I
made 5 times tests, every time is the same). And then, after that, the
insertion to tracking table will be every slow, probably 2-3 rows/sec.
My hbase version is 0.92.0. Can anyone tell me why and how I can
increase the speed?
