s1ck opened a new pull request #24490: [SPARK-27300][GRAPH] Add Spark Graph modules and dependencies
URL: https://github.com/apache/spark/pull/24490
 
 
   Co-authored-by: Sören Reichardt <so...@neotechnology.com>
   
   ## What changes were proposed in this pull request?
   
   This PR introduces the necessary Maven modules for the new [Spark Graph](https://issues.apache.org/jira/browse/SPARK-25994) feature for Spark 3.0.
   
   * `spark-graph` is a parent module that users depend on to get all graph functionalities (Cypher and Graph Algorithms)
   * `spark-graph-api` defines the [Property Graph API](https://docs.google.com/document/d/1Wxzghj0PvpOVu7XD1iA8uonRYhexwn18utdcTxtkxlI) that is being shared between Cypher and Algorithms
   * `spark-cypher` contains a Cypher query engine implementation
   
   Both, `spark-graph-api` and `spark-cypher` depend on Spark SQL.
   
   Note, that the Maven module for Graph Algorithms is not part of this PR and will be introduced in https://issues.apache.org/jira/browse/SPARK-27302
   
   A PoC for a running Cypher implementation can be found in this WIP PR https://github.com/apache/spark/pull/24297
   
   ## How was this patch tested?
   
   There is a `DummySuite` in `spark-cypher` to enforce building the modules.
