Open Letter to the SciDB Community - Release 11.06 is Available
June 15, 2011
Starting with the June 2011 release, we are adopting a <year.month> naming convention for releases, following the lead of many open source projects.
The new release, R11.06, is effectively a R1.0. Highlights of this release include:
- Expanded set of AQL (array query language) and AFL (array functional language) operations including array joins
- More data loading support including a redimension function which is useful for loading csv formatted data into multi-dimensional arrays
- Updates and versioning (with thanks to NSF-supported work by Adam Seering)
- User-defined types and functions
- Python connector (with thanks to volunteers Mike Fabbri and the Persistent Systems team)
- Support for RedHat in addition to Ubuntu
The source code and documentation are available for download at SciDB Forum. Documentation can be found in the wiki. The forum also contains useful Q&A.
This release includes a test suite with nearly 900 AFL and AQL scripts and many examples illustrating the use of AFL and AQL. If you find a bug, please report it along with a simple test case on the forum. The SciDB project team will validate it before logging it in the trac system.
We are also pleased to announce the addition of Nikolay Malitsky, from the EPICS project at Brookhaven National Labs, to our Science Advisory Board. EPICS, which stands for Experimental Physics and Industrial Control System, is an international collaboration encompassing a long list of large-scale scientific projects. They have begun evaluating SciDB for the new EPICS Archiver which will be scaling towards data rates of 1 million samples per second.
For the next release we will be focusing on speed and scalability including further improvements to the storage manager.
We hope the community will start using this release on substantial data sets. Share your feedback and requests with us on the forum.
The SciDB Team
