This week, the open-source community released Apache Accumulo 1.6. The newest Accumulo release brings with it a whole slew of new features, performance improvements, and bug fixes. Check out the full release notes and read below for a quick recap of some of the themes.
1.6 by the Numbers
- Multiple Volume Support – Accumulo can now span across distinct instances of HDFS, allowing for greater scalability and performance
- In-Memory Locality Groups – In-memory partitioning is now locality group aware, which benefits reads and minor compactions
- Pluggable Compaction – An administrator can now set custom compaction strategies, allowing you to specify which files and when to compact
- Table Namespaces – Allows for grouping of Accumulo tables into logical collections
- Lexicoders – Facilitates serialization for complex key tuples
- Conditional Mutations – Accumulo now offers a way to make atomic check-and-set operations from the client side
- New Maven Plugin – the 1.6 Maven plugin includes a feature to start up a MiniAccumuloCluster during the integration test phase of the lifecycle
Sqrrl has contributed back to the community a number of the improvements we’ve made to security in Accumulo, including pluggable encryption for write-ahead logs, pluggable encryption for RFiles, and encryption in motion.
We’re extremely proud to be part of the community building and supporting Apache Accumulo. Accumulo 1.6 will ship with our next release, Sqrrl Enterprise 1.4.
Stay tuned for more exciting announcements about our 1.4 release, and check out the inaugural Accumulo Summit coming up next month in College Park, MD!
