Utils for bridging Apache Arrow and PostgreSQL's wire protocol.

Convergence

A set of tools for writing servers that speak PostgreSQL's wire protocol.

🚧 This project is extremely WIP at this stage.

Crates

convergence contains the core traits, protocol handling and connection state machine for emulating a Postgres server.

convergence-arrow enables translation of Apache Arrow dataframes into Postgres result sets, allowing you to access your Arrow-powered data services via standard Postgres drivers. It also provides a reusable Engine implementation using DataFusion for execution.
