Hi, Stack I have not test the performance in big cluster, yet. I just test it in two node using my c++ project. One node is holding HMaster and Zookeeper server, the other is holding HRegionServer. My scan performance is about 5293 records per second. When I get those data from a local file, the performance is 208757 records per second. PS. the data are stored as a tree in the file.
I have meant to get a better read performance through hbase, but actually I get an opposite result. Could you give me any advices to deal with it? Maybe some tuning tips or usage tips of HBase with c++.
