leventov opened a new issue #7858: Turn ImmutableDruidDataSource into a data container
URL: https://github.com/apache/incubator-druid/issues/7858
 
 
   `ImmutableDruidDataSource`'s `equals()` and `hashCode()` should throw `UnsupportedOperationException` as well as `DruidDataSource`'s methods do. `ImmutableDruidDataSource` should be considered a *container, not a data class*.
   
   The idea is the same as behind prohibiting/limiting `equals()` (and therefore usage as `HashSet`/`HashMap` keys) of `DataSegment`: see #6358. When somebody wants to deduplicate `ImmutableDruidDataSource` objects, they would need to put them into a `Map<String, ImmutableDruidDataSource>` and resolve conflicts by name manually.
