Hi , Need to calculate data size in HBase. I can do it by using KV length. But it is time consuming with huge data block. HFile looks better solution but still I have question with HFile, HFile will give size of data block. What if I have limit in scan[ ] object start row and end row. And those range can be some where in two different HFile. To calculate exact size I need to use loop, which is again inefficient. Actually, I am trying to run map reduce using HBase as source. I need to know what is data size. I am trying to do some performance evaluation. Still I can do some approximation calculation, looking at map-reduce input. It is always better to know exact size.
Do you know how can do calculate data size in HBASE. -- With Best Regards Bikash Agrawal Web/Software Developer Mobile: +47 92502701 www.bikashagrawal.com.np
