Interface DataSourceConfiguration

All Known Implementing Classes:

TableConfig

public interface DataSourceConfiguration

Holds the minimum necessary configuration to set up fili to make requests to druid. This defines all metrics, dimensions, *one* valid time grain, and data segments of a datasource. Note the restriction to one time grain, a druid datasource could have more than one, but it *should* have just a single grain.
