Overview

Microservice Native Event Store and Message Store for Postgres

A fully-featured event store and message store implemented in PostgreSQL for Pub/Sub, Event Sourcing, Messaging, and Evented Microservices applications.

Message DB supports:

• Pub/Sub
• JSON message data
• Event streams
• Stream categories
• Metadata
• Message queues
• Message storage
• Consumer groups
• Service host
• Administration tools
• Reports

The message store provides functions for writing messages to streams, and reading messages from entity streams and category streams. Messages are stored in a single table.

The Eventide toolkit's message store library provides a Ruby interface to the Message DB message store database, and the messaging library provides a message-oriented interface with support for message transformation to and from JSON, message handling, and affordances for metadata and more advanced messaging patterns.
