Milestone Releases

2011 Q2 (v1.0.0 : Performance)

• Smaller on disk footprint and faster data load.
• A new persistence store which scales to ~50B triples/quads on a single machine.
• A new query engine. It's faster, has a smaller footprint in memory and is more extensible.
• 100% native SPARQL evaluation.
• Easy start install.
• Released on 7/5/2011.

2011 Q4 (v1.1.0 : Analytics)

• SPARQL 1.1 support (Sesame 2.5) (except property paths and update).
• Scalable analytic operators.
• New extensible hash tree index.
• Memory manager to relieve the JVM heap pressure. 100% native Java solution gets data off the JVM object heap.
• Much faster query plans for complex optional groups and UNION.
• BLOBs index (large literal and large URI support).

2012 Q1 (v1.2.0)

• SPARQL 1.1 UPDATE
• SPARQL 1.1 Service Description
• SPARQL 1.1 Basic Federated Query

• Remote Java client for NanoSparqlServer
• Sesame 2.6.3 dependency
• Ganglia integration (cluster)
• Performance improvements (cluster)

2013 Q1 (v1.2.3)

• SPARQL 1.1 Update Extensions (solution sets, cache control).
• SPARQL 1.1 Property Paths.

2013 Q2 (v1.3.0)

• Highly Available Replication Cluster

Unscheduled Features

• Spatial indices.
• Query time inference.
• Embedded prolog engine.
• GPU enabled analytics.
• Stream database extensions.
