# rpubsub

Reliable implementation of [Publish–subscribe messaging pattern][1] backed by [Redis Streams][2].

## Installation

```bash

$ go get -u github.com/RussellLuo/rpubsub

```

## Motivation

- Learn [Redis Streams][2] by doing.

- Implement a more reliable Publish–subscribe messaging mechanism than [Pub/Sub][3].

## Design & Implementation

- Publishing

    + Just use [XADD][4] directly.

- Subscribing

    + API (inspired by [Principles of designing Go APIs with channels][5]).

    + [Blocking][6] instead of polling (which means one goroutine per topic).

- Snapshotting

    + Built-in snapshotters ([NilSnapshotter][7] and [RedisSnapshotter][8]).

    + Save point (inspired by Redis's [RDB persistence][9]).
