Log Message:
-----------
This is a bigdata (R) snapshot release. This release is capable of loading 1B
triples in under one hour on a 15 node cluster and has been used to load up to
13B triples on the same cluster. JDK 1.6 is required.
See [1] for instructions on installing bigdata(R), [2] for the javadoc and [3]
and [4] for news, questions, and the latest developments. For more information
about SYSTAP, LLC and bigdata, see [5].
Please note that we recommend checking out the code from SVN using the tag for
this release. The code will build automatically under eclipse. You can also
build the code using the ant script. The cluster installer requires the use of
the ant script. You can checkout this release from the following URL:
https://bigdata.svn.sourceforge.net/svnroot/bigdata/branches/BIGDATA_RELEASE_0_83_1
New features:
- Inlining XSD numerics, xsd:boolean, or custom datatype extensions
into the statement indices. Inlining provides a smaller footprint
and faster queries for data using XSD numeric datatypes. In order
to introduce inlining we were forced to make a change in the
physical schema for the RDF database which breaks binary
compatibility for existing stores. The recommended migration path
is to export the data and import it into a new bigdata instance.
- Refactor of the dynamic sharding mechanism for higher performance.
- The SparseRowStore has been modified to make Unicode primary keys
decodable by representing Unicode primary keys using UTF8 rather
than Unicode sort keys. This change also allows the SparseRowStore
to work with the JDK collator option which embeds nul bytes into
Unicode sort keys. This change breaks binary compatibility, but
there is an option for historical compatibility.
The roadmap for the next releases include:
- Query optimizations;
- Support for high-volume analytic query workloads and SPARQL aggregations;
- High availability for the journal and the cluster;
- Simplified deployment, configuration, and administration for clusters.

About bigdata:
Bigdata?\194?\174 is a horizontally-scaled, general purpose storage and computing fabric
for ordered data (B+Trees), designed to operate on either a single server or a
cluster of commodity hardware. Bigdata?\194?\174 uses dynamically partitioned key-range
shards in order to remove any realistic scaling limits - in principle, bigdata?\194?\174
may be deployed on 10s, 100s, or even thousands of machines and new capacity may
be added incrementally without requiring the full reload of all data. The bigdata?\194?\174
RDF database supports RDFS and OWL Lite reasoning, high-level query (SPARQL),
and datum level provenance.
