Hi, Looking in the archives, there's an old thread on this topic: http://mail-archives.apache.org/mod_mbox/hbase-user/201407.mbox/%3c1405526793.13450.yahoomail...@web140605.mail.bf1.yahoo.com%3E
Three important takeaways: 1. From that aspect HBase clusters with less than 9 RegionServers are not really useful. 2. We have 1ge everywhere so far, and we found this is a single most bottleneck for write performance. 3. You can store about 2T of effective data per node in HBase, unless you have a mostly read-only load. Are these still valid in newer releases? -- Thanks, Gunnar *If you think you can you can, if you think you can't you're right.*
