Wukong for Linked Data

Wukong is a fast and distributed graph-structured store that leverages efficient graph exploration to proivde highly concurrent and low-latency query processing over big linked data.

Feature Highlights

  • High-performance and scalable in-memory graph store
  • Fast and concurrent query processing by graph exloration
  • Fast communication by leveraging RDMA feature of InfiniBand network
  • (coming soon) A GPU extension of query engine for heterogenous (CPU/GPU) cluster
  • (coming soon) Fast and accurate SPARQL query plan optimizer

For more details see Wukong Project, including new features, roadmap, instructions, etc.
