Granularity (Apache Calcite API)

All Superinterfaces:

DruidJson

All Known Implementing Classes:

Granularities.AllGranularity, Granularities.PeriodGranularity
```
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.
