databento-dbn
Python bindings for encoding and decoding Databento Binary Encoding (DBN)
Decision gist · record as of 2026-08-14
Yes, if you are using the Databento Python client library or need to work directly with DBN-encoded financial data. The package is actively maintained, has no known vulnerabilities, and offers good platform coverage. Install it only if you have a specific need for DBN encoding/decoding; it is not a general-purpose library and is explicitly marked as for advanced users.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; precompiled wheels available for common platforms, but building from source requires Rust and Maturin.
- Medium install friction due to compiled Rust bindings, but well-supported across Python 3.10+ on major platforms (macOS, Linux, Windows).
- Active maintenance with a recent release (3 days old) and no known vulnerabilities.

What it is and what it does
databento-dbn is a low-level Python library that wraps Databento's Rust implementation of DBN, a binary encoding format for financial market data. It is designed primarily as an internal dependency of the Databento Python client library and is intended for advanced users who need direct access to DBN encoding and decoding operations.
The package provides bindings to serialize and deserialize market data in DBN format, which is optimized for compact storage and fast transmission of time-series financial information. It has no runtime dependencies and is distributed as precompiled wheels for Python 3.10, 3.11, and 3.12 across macOS, Linux, and Windows, making installation straightforward on standard platforms.
Use it for
- Decode DBN-encoded market data received from Databento's data feeds or stored files
- Encode market data into DBN format for efficient storage or transmission
- Integrate with the Databento Python client library for advanced data handling workflows
- Build custom market data processing pipelines that require direct access to DBN serialization
