Thanks to all developers!

What is janusgraph-externals?

janusgraph-externals is an unofficial collection of external toolkits built around janusgraph. The purpose is to make janusgraph more convenient and efficient to use, including the following modules.

• janusgraph-graphx
  janusgraph-graphx built on top of Apache Spark GraphX and JanusGraph. The purpose is to integrate these two components. Spark generates RDD by parsing the underlying HFile of JanusGraph and deserializing the JanusGraph vertex-edge structure. Welcome developers to test and upgrade iteratively together. (This is a basic version adapt to janusgraph-0.5.2, other versions need to be tested)

• janusgraph-seatunnel
  janusgraph-seatunnel built on top of SeaTunnel. The purpose is to improve the efficiency of batch import and export of JanusGraph data.(Coming soon)

• janusgraph-chinese-doc
  JanusGraph Chinese Document

Stay tuned for more content! (For example: Spark writes into JanusGraph by generating HFile, visual query platform, etc. Developers are also welcome to contribute!)

JanusGraph Q&A

Ask Question

• The vertex-center-index will be created automatically, so there is no need for user customization?
• If I add attributes to the edge, will janusgraph automatically create a local index? Do I not need to define a schema?
• Where does the vertex-center-index exist? What is the principle？
• JanusGraph's profile() cannot display the vertex-centic index. Is it applied?
• JanusGraph causes memory overflow problem.
