This Apache Druid module extends [Druid Hadoop based indexing](../../ingestion/hadoop.md) to ingest data directly from offline
Apache Parquet files.

Note: If using the `parquet-avro` parser for Apache Hadoop based indexing, `druid-parquet-extensions` depends on the `druid-avro-extensions` module, so be sure to
 [include  both](../../configuration/extensions.md#loading-extensions).

The `druid-parquet-extensions` provides the [Parquet input format](../../ingestion/data-formats.md#parquet), the [Parquet Hadoop parser](../../ingestion/data-formats.md#parquet-hadoop-parser),
and the [Parquet Avro Hadoop Parser](../../ingestion/data-formats.md#parquet-avro-hadoop-parser) with `druid-avro-extensions`.
The Parquet input format is available for [native batch ingestion](../../ingestion/native-batch.md)
and the other 2 parsers are for [Hadoop batch ingestion](../../ingestion/hadoop.md).
Please see corresponding docs for details.
