Subject Tuning HBase for random reads
Date Wed, 26 Sep 2012 06:04:29 GMT

I am running hbase-0.92.1 and have set up a cluster of 10 machines. Scans
performance seems great, 30K-100K rows per second, but random row reads are
only about 100 rows/second.

My rows are not very big, just a few columns with between 4-100 bytes, but
my table is around 18M rows.

I am pre-splitting my table and using hashing to randomize the row keys, so
I see a nice even load on the region servers.

Any suggestion on things I should try?
