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.

In this panel we will discuss the merits of some of these tools and what to look for when selecting a tool for a given project. What are the benefits of compiling to JavaScript as opposed to coding in it? What are the core differences between different MVC solutions? What are the tradeoffs that you make when you use an integrated framework that runs on both the client and server side? What about testing, security, and continuous integration?

From the abstract: “By now, it’s no secret that asynchronous and non-blocking code means fast and responsive software stacks that scale to the moon. The only problem? Asynchronous code usually means callback hell that’s impossible to write, impossible to reason about, and even worse to maintain. Not any more— Scala 2.10 brings an asynchronous, completely non-blocking, composable Futures and Promises API. And best yet? Code using it looks sequential— nice and easy to reason about. In this talk, I’ll show…
