SYSTAP is very pleased to launch it’s new graph database platform Blazegraph™ with the 1.5.0 software release available now on Sourceforge. It is built on the same platform and maintains 100% binary and API compatibility with Bigdata®. Blazegraph™ will take over as SYSTAP’s flagship graph database.
This is an overview of the Blazegraph™ roadmap. Features and release dates are subject to change.
