hbase: All content about hbase in NoSQL databases and polyglot persistence
- Uses Guice to load modules.
- Incorporates Jetty for Rest API and serving up UI.
- Pure Java build tool (Tablesaw)
- UI uses Flot and is client side rendered.
- Ability to customize UI.
- Relative time now includes month and supports leap years.
- Modular data store interface supports:
- H2 (For development)
- Milliseconds data support when using Cassandra.
- Rest API for querying and submitting data.
- Build produces deployable tar, rpm and deb packages.
- Linux start/stop service scripts.
- Made aggregations optional (easier to get raw data).
- Added abilities to import and export data.
- Aggregators can aggregate data for a specified period.
- Aggregators can be stacked or “piped” together.
Source code lives on GitHub. Let’s see where it goes.

Interesting slidedeck by Matthias Broecheler introducing 3 graph-related tools developed by Vadas Gintautas, Marko Rodriguez, Stephen Mallette and Daniel LaRocque:
- Titan: a massive scale property graph allowing real-time traversals and updates
- Faunus: for batch processing of large graphs using Hadoop
- Fulgora: for global running graph algorithms on large, compressed, in-memory graphs
The first couple of slides are also showing some possible use cases where these tools would prove their usefulness:

Released by the Salesforce team, Phoenix adds a SQL layer on top of HBase and an almost complete JDBC driver.
Direct use of the HBase API, along with coprocessors and custom filters, results in performance on the order of milliseconds for small queries, or seconds for tens of millions of rows.
