Introduction

EntDB is a Rust-based SQL database engine with PostgreSQL wire compatibility.

It runs in two modes:

  • embedded library (entdb crate),
  • server (entdb-server) for psql and pg drivers.

Current scope

  • Core DDL/DML for OLTP-style workloads.
  • MVCC transactions.
  • WAL + restart recovery.
  • Optional polyglot SQL ingress on both server and embedded paths. When enabled, EntDB rewrites selected non-PostgreSQL SQL forms (for example MySQL backticks and numeric LIMIT offset, count) into PostgreSQL-compatible SQL before parsing.

See quickstart.md for usage and architecture.md for runtime layout.
