The granularity field determines how data gets bucketed across the time dimension, or how it gets aggregated by hour, day, minute, etc.
Granularity determines how to bucket data across the time dimension, or how to aggregate data by hour, day, minute, etc.
It can be specified either as a string for simple granularities or as an object for arbitrary granularities.
For example, use time granularities in [native queries](querying.md) to bucket results by time, and in the `dataSchema` \\ [`granularitySpec`](../ingestion/ingestion-spec.md#granularityspec) section of ingestion specifications to segment incoming data.
You can specify a time period as a [simple](#simple-granularities) string, as a [duration](#duration-granularities) in milliseconds, or as an arbitrary ISO8601 [period](#period-granularities).
