Talk lists the current status of HBase, what has been added, improved, or fixed in the recent releases. Outlook on what is coming next.
This talk explains the current status of HBase, and how it has improved over the last recent releases. It discusses the most important fixes and additions, how they impact the stability and performance of HBase, and what the developers are currently working on.
In more detail: the talk focuses on what happened to HBase since version 0.90. The idea is to introduce and discuss all the major changes in 0.92, 0.94, and trunk, aka 0.96. This spans from coprocessors and security, to distributed log splitting in 0.92, to prefix compression and lazy seek optimizations in 0.94 and so on. But also more subtle - yet often equally important - features like WALPlayer, or the handling of checksums, are presented as they improve operations and performance. The goal is to show the audience the large strides HBase and its community have taken towards a 1.0 release.
