# Changelog



## Unreleased



### Added



- Initial remote DuckDB Quack protocol client backed by `DBConnection`.

- Binary Quack protocol codec with message, logical type, data chunk, vector, and scalar decoding support.

- HTTP transport for Quack endpoints.

- Query execution, prepare/execute, fetch continuation, streaming, and transaction support.

- Decoding for common scalar DuckDB types and nested result values including `LIST`, `STRUCT`, `ARRAY`, and `MAP`.

- Command result normalization for DuckDB `Count` outputs into affected-row `num_rows`.

- Compact `Inspect` implementations for easier IEx debugging.

- Initial Ecto SQL adapter support for raw `Repo.query/3`, transactions, and simple read-only `Repo.all/2` table queries.

- Gated real DuckDB Quack integration tests.



### Notes



- QuackDB itself is experimental: package APIs, result shapes, Ecto behavior, and supported type coverage may change before the project stabilizes.

- QuackDB follows DuckDB's experimental Quack protocol behavior.

- Ecto support is intentionally limited; joins, grouped queries, migrations, and Ecto-managed writes are not supported yet.
