I don't know the history, but it seems that the site itself announces a false news. According to the our dev mailing list, there is no evidence for the followings. > Databricks and Neo4j contributors have proposed to integrate the openCypher language into Apache Spark 3.0 to become a central piece of a new graph module in Apache Spark 3.0, driven through the openCypher project Cypher for Apache Spark @mengxr already told us that he is an individual to work on this. So, if you want to keep this link, you must remove the announce on the site. In general, I know that it's beyond of this PR scope, so, you can remove this link from the PR for now. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
