| 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](../../development/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. |
