Subject [Hadoop Wiki] Update of "Hbase/HbaseRTDS" by Misty
Date Thu, 22 Oct 2015 21:33:51 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "Hbase/HbaseRTDS" page has been changed by Misty:
https://wiki.apache.org/hadoop/Hbase/HbaseRTDS?action=diff&rev1=9&rev2=10

+ The HBase Wiki is in the process of being decommissioned. The info that used to be on this
page has moved to http://hbase.apache.org/book.html#performance. Please update your bookmarks.

- = Validating the Real-time Performance of Hbase =
  
- I've done some very simple benchmarks that seeks to find out if hbase is suitable for real
time data serving.
- 
- All benchmarks run with hadoop 0.15.1, 3 datanodes and regionservers. One of them served
as master (not ideal, I know).
- 894621 values were put in the table column retrieved. One separate machine acted as the
client, it picked a random key known to be in the dataset and requested that.
- 
- The results are very similar to just reading values from a MapFile on the HDFS, suggesting
that the performance bottlenecks are not in HBase itself.
- Not sure why the requests / second graph is so jumpy.
