Convergence
A set of tools for writing servers that speak PostgreSQL's wire protocol.
๐ง 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.
