My HBase colleagues and I have been working hard on the next generation of HBase - the upcoming 0.20 release! We recently published an alpha release and are working on stabilizing and testing for the final 0.20 release candidate.
The release sports many new and cool features:
- New file format offers improved efficiency and features
- New read paths are faster and less memory intensive
- Zookeeper integration - allows multiple masters
- New API, better delete semantics, improved caching, and more!
In addition to code, I've also taken a bit of time out to speak at a recent conference here in SF. There were some other great projects speaking, all videotaped and uploaded. Check it out, lots of smart people talking on some fascinating subjects.
