Compression

Databento provides options for compressing files from our API. Available compression formats depend on the encoding you select.

Zstd

The Zstd compression option uses the Zstandard format.

This option is available for all encodings, and is recommended for faster transfer speeds and smaller files.

You can read Zstandard files in Python using the zstandard package.

None

The None compression option disables compression entirely, resulting in significantly larger files. However, this can be useful for loading small CSV files directly into Excel.
