After Druid reads the input data records, it applies the flattenSpec before applying any other specs such as [`timestampSpec`](./ingestion-spec.md#timestampspec), [`transformSpec`](./ingestion-spec.md#transformspec),
> [`dimensionsSpec`](./ingestion-spec.md#dimensionsspec), or [`metricsSpec`](./ingestion-spec.md#metricsspec). Keep this in mind when writing your ingestion spec.

This makes it possible to extract timestamps from flattened data, for example, and to refer to flattened data in transformations, in your dimension list, and when generating metrics.
Flattening is only supported for [data formats](data-formats.md) that support nesting, including `avro`, `json`, `orc`,
and `parquet`.
