Introduction to Apache HBase Snapshots, Part 2: Deeper Dive

In Part 1 of this series about Apache HBase snapshots, you learned how to use the new Snapshots feature and a bit of theory behind the implementation. Now, it’s time to dive into the technical details a bit more deeply.

What is a Table?

An HBase table comprises a set of metadata information and a set of key/value pairs:

The HBaseCon 2013 Afterglow

HBaseCon 2013 is in the books. Thanks to all our speakers, sponsors, and attendees! A great time was had by all.

For those of you who missed the show, session video and presentation slides (as well as photos) will be available via hbasecon.com in a few weeks. (To be notified, follow @cloudera or @ClouderaEng.) Although it’s not quite as good as being there with the rest of the community, you’ll still be able to partake from the real-world experiences of Apache HBase users like Facebook, Box, Yahoo!, Salesforce.com, Pinterest, Twitter, Groupon, and more.

Customer Spotlight: It’s HBase Week!

This is the week of Apache HBase, with HBaseCon 2013 taking place Thursday, followed by WibiData’s KijiCon on Friday. In the many conversations I’ve had with Cloudera customers over the past 18 months, I’ve noticed a trend: Those that run HBase stand out. They tend to represent a group of very sophisticated Hadoop users that are accomplishing impressive things with Big Data. They deploy HBase because they require random, real-time read/write access to the data in Hadoop. Hadoop is a core component of their data management infrastructures, and these users rely on the latest and greatest components of the Hadoop stack to satisfy their mission-critical data needs.

Today I’d like to shine a spotlight on one innovative company that is putting top engineering talent (and HBase) to work, helping to save the planet — literally.

HBaseCon 2013 is this Thursday (June 13 in San Francisco), and we can hardly wait!

What’s Next for HBase? Big Data Applications Using Frameworks Like Kiji

Michael Stack is the chair of the Apache HBase PMC and has been a committer and project “caretaker” since 2007. Stack is a Software Engineer at Cloudera.

Apache Hadoop and HBase have quickly become industry standards for storage and analysis of Big Data in the enterprise, yet as adoption spreads, new challenges and opportunities have emerged. Today, there is a large gap — a chasm, a gorge — between the nice application model your Big Data Application builder designed and the raw, byte-based APIs provided by HBase and Hadoop. Many Big Data players have invested a lot of time and energy in bridging this gap. Cloudera, where I work, is developing the Cloudera Development Kit (CDK). Kiji, an open source framework for building Big Data Applications, is another such thriving option. A lot of thought has gone into its design. More importantly, long experience building Big Data Applications on top of Hadoop and HBase has been baked into how it all works.

Kiji provides a model and set of libraries that help you get up and running quickly.

CDH 4.3: Now Shipping with More Apache HBase Improvements

As you may know, Apache HBase has a vibrant community and gets a lot of contributions from developers worldwide. The collaborative development effort is so active, in fact, that a new point-release comes out about every six weeks (with the current stable branch being 0.94).

At Cloudera, we’re committed to ensuring that CDH, our open source distribution of Apache Hadoop and related projects (including HBase), ships with the results of this steady progress. Thus, CDH 4.2 was rebased on 0.94.2, as compared to its predecessor CDH 4.1, which was based on 0.92.1. CDH 4.3 has moved one step further and is rebased on 0.94.6.1.

HBaseCon 2013: "Ecosystem" Track Preview

Unbelievably, HBaseCon 2013 is only one week away (June 13 in San Francisco)!

HBaseCon 2013: "Internals" Track Preview

As we march toward HBaseCon 2013 (June 13 in San Francisco), it’s time to bring you a preview of the Internals track (see the Operations track preview here) — the track guaranteed to be of most interest to Apache HBase developers and other people tracking the progress of the code base.

HBaseCon 2013: "Operations" Track Preview

As you have probably learned by now, HBaseCon 2013 sessions are organized into four tracks: Operations, Internals, Ecosystem, and Case Studies. In combination, they offer a 360-degree view of Apache HBase that is invaluable for experts and aspiring experts alike. In the next few posts leading up to the conference (June 13 in San Francisco – register now while there’s still room), we’ll offer sneak previews of what each track has to offer.
