Yes, it is implemented and already went live in several big companies in bay area.
Spark Python is being used as the language for doing the typical data transformation jobs when necessary. It is totally optional. The data are stored in a Incorta proprietary format when they are presented in memory and ready to serve the query requests. When the data are stored in disk, the data are first prepared in Parquet as staging area, but will be backed up as memory dump. Typically a star schema is required for handling the data in a relational database. The star schema is a modeling design to speed up the query performance. You do not need to do that when the data is presented in memory. There are better way than doing the joins using (bitmap) indexes, surrogate key, etc. That is Incorta Hope this helps.
