package org.apache.spark.sql.sources.v2; public interface DataSourceV2 {} |
Note
|
Implementations should mix-in at least one of the interfaces like ReadSupport and WriteSupport . Otherwise it’s simply a dummy data source which is un-readable and un-writable.

Note
|
In other words, using the contract is as treading on thin ice. |
