I am currently running under Hbasev0.20.3. I increased the block cache to .4 from .2. The heap size is 2GB. The default regionserver handler count is 25 in hbase-default.xml. Will try LZO compression.
What are other performance tunings I can do ? In particular, will applying HBASE-2180 or upgrading to a newer version help ? Another thing I notice is that the performance via stargate vs Java api is comparable for random reads.I thought stargate would have some latency. Is this expected? Thanks, Avani
