From the abstract: “This talk will address valuable lessons learned with the current versions of HBase. There are inherent architectural features that warrant for careful evaluation of the data schema and how to scale out a cluster. The audience will get a best practices summary of where there are limitations in the design of HBase and how to avoid those. In particular, we will discuss issues like proper memory tuning (for reads and writes), optimal flush file sizing, compaction tuning, and the number of write ahead logs required. Further, there is a discussion of the theoretical write performance, in comparison to those observed on real clusters. A collection of cheat sheets and example calculation for cluster sizing rounds out the talk towards the end.”
