Subject Re: SPIP: DataFrame-based Property Graphs, Cypher Queries, and Algorithms
Date Sun, 20 Jan 2019 14:30:50 GMT
I support the proposal. I am assisting various companies as a system
integrator of Neo4j. There is several Japanese telecommunications companies
quickly grasping the state of the network topology. In addition, many
advertising censure companies associate enormous metadata and use it for
marketing using Neo4j and Cypher query. Cypher Query's flexible search and
extraction mechanisms benefit from these activities. Also, many
manufacturing industries in Japan interest in the graph database model. We
believe that support of Cypher Query in Apache Spark can give Japanese
graph data users a more convenient path to distributed processing.
In Japan, communities that love Neo4j, Cypher Query are already active and
frequently communicating. ( https://jp-neo4j-usersgroup.connpass.com/ )
With Cypher Query support from Apache Spark, they will be encouraged and
will love Apache Spark. We are convinced that the Apache Spark developer
community will expand further.

Regards,
