Depending on which format you want to use you need to install one or more of the following libraries.

Avro:

pip install fastavro

Avro is a file format.

Iceberg:

pip install pyiceberg pyarrow pandas

Iceberg is an open table format.

Note: Most likely you will need to add specific dependencies so that Iceberg works for you. See pyiceberg installation

ORC:

pip install pyarrow pandas

ORC is a file format.

Parquet:

pip install pyarrow pandas

Parquet is a file format.

Additional libraries may be needed for specific compression algorithms. The open table format may require additional libraries also to use different filesystems, catalogs and compression formats. See “Use”.

Use

Use of the library is simple. Install it with your Scrapy project as described above.You only need to configure the exporter in the Scrapy settings, run your scraper and the data will be exported into your desired format. There is no development needed.
