Cockroach to AMQP bridge

Sync change data to RabbitMQ from CockroachDB

Introduction

For traditional database, we have Canal, Maxwell for mysql, or pg-amqp-bridge for Postgresql, to synchronize change data from database to rabbitmq.

This tool achieves same feature via experimental core changefeed for CockroachDB.

Configuration is done through environment variables:

• DATABASE_URL: e.g. postgresql://username:password@domain.tld:port/database

• TABLES: e.g. users,orders,goods
