Bridge to replicate NATS Subjects or Channels to NATS Subject or Channels

NATS Replicator

This project implements a multi-connector bridge, copier, replicator between NATS and NATS streaming endpoints.

Features

• Arbitrary subjects in NATS, wildcards for incoming messages
• Arbitrary channels in NATS streaming
• Optional durable subscriber names for streaming
• Configurable std-out logging
• A single configuration file, with support for reload
• Optional SSL to/from NATS and NATS streaming
• HTTP/HTTPS-based monitoring endpoints for health or statistics

Overview

The replicator runs as a single process with a configured set of connectors mapping a between a NATS subject or a NATS streaming channel. Each connector is a one-way replicator.

Connectors share a NATS connection and an optional connection to the NATS streaming server.

Request-reply is not supported.

The replicator is configured with a NATS server-like format, in a single file and uses the NATS logger.

An optional HTTP/HTTPS endpoint can be used for monitoring.
