Apache Ignite is a distributed database management system for high-performance computing with in-memory speed. Posting this idea to gauge interest in the development of a formal format.
Note: FME can likely connect to this database already via the JDBC Reader/Writer as Ignite has a driver that you can download here: https://ignite.apache.org/docs/latest/SQL/JDBC/jdbc-driver
FME's JDBC Reader/Writer documentation: https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_ReadersWriters/jdbc/jdbc.htm
