jedge's Introduction

Jedge

unofficial Edgedb database connector for Java

(!) CAUTION: this library is work in progress and nowhere near production-ready (even simple parsers for basic types are missing right now)

details

This package contains a database connector for edgedb in java.

Features

connection to edgedb via TLS/SASL Authentification
wireformats: json, binary
parser support for binary protocol
Milkman integration (see readme)

Usage

if you want to use binary protocol and included parsers, you can do so like this:

public class JedgeBinaryMapperTest {

  public static void main(String[] args) throws Exception {

    SimpleTypeRegistry typeRegistry = new SimpleTypeRegistry();
    JedgeBinaryMapper mapper = new JedgeBinaryMapper(typeRegistry);
    try(var jedge = new Jedge(WireFormat.BinaryFormat, typeRegistry)) {
      jedge.connect(Dsn.fromString("edgedb://edgedb:password@localhost:10701/edgedb"));
      for (ResultType result : jedge.queryList("select Movie { title, year };", mapper.deserializerFor(ResultType.class))) {
        System.out.println("Received result: " + result);
      }
    }
  }

  @lombok.Data
  public static class ResultType {
    private UUID id;
    private String title;
    private Long year;
  }
}

Installation

in maven, include it via jitpack:
