Also, LDBC announced public drafts of its two first benchmarks. Public draft means that implementations of benchmark software and technical specification documents are available, and ready for public testing and comments. The two benchmarks are

– the Social Network Benchmark (SNB – http://ldbcouncil/benchmarks/snb) on which an interactive workload has been released.

The SNB data generator was recently used in the ACM SIGMOD programming contest, which was about graph analytics.

The website also holds a blog with new and technical backgrounds of LDBC. The most recent post is about “Choke-Point based Benchmark Design”, by Peter Boncz.
