I see two connectors in MEP 3.0 and both of them might work for our use case. Have few questions that may help further clarify which options is best for us.


1) Native Spark Connector for MapR-DB JSON

Are following scala DSL predicates gets pushdown to datasource?

2) Spark HBase and MapR-DB Binary Connector

Would this work over mapr-db binary tables ? does it do predicate pushdown and projection? If so what is the difference between this one and previous connector? Performance? This one also supports spark dataframe which is more programmer friendly and performant with spark 2.
