Hi, I am evaluating Spark for an analytic component where we do batch processing of data using SQL.
So, I am particularly interested in Spark SQL and in creating a SchemaRDD from an existing API [1]. This API exposes elements in a database as datasources. Using the methods allowed by this data source, we can access and edit data. So, I want to create a custom SchemaRDD using the methods and provisions of this API. I tried going through Spark documentation and the Java Docs, but unfortunately, I was unable to come to a final conclusion if this was actually possible. I would like to ask the Spark Devs, 1. As of the current Spark release, can we make a custom SchemaRDD? 2. What is the extension point to a custom SchemaRDD? or are there particular interfaces? 3. Could you please point me the specific docs regarding this matter? Your help in this regard is highly appreciated.
