Interface Granularity

All Superinterfaces:

DruidJson

public interface Granularity
extends DruidJson

A strategy by which Druid rolls up rows into sub-totals based on their timestamp values.

Typical granularities are based upon time units (e.g. 1 day or 15 minutes). A special granularity, all, combines all rows into a single total.

A Granularity instance is immutable, and generates a JSON string as part of a Druid query.
