# Slim 

Slim is an AMQP-based ordered commit log (think Apache Kafka) with focus on a simple interface, keeping a small footprint, and providing decent performance.

Slim does not offer features such as TLS, replication or authentication.

Slim can be used in combination with other AMQP components such as the [Apache Qpid Dispatch Router](https://qpid.apache.org/components/dispatch-router/index.html) to provide TLS, authentication and load balancing across multiple instances (at the expense of ordering).

The event log can be limited by time or not at all (by size will be added).

Producers send AMQP messages to a topic. The messages are stored immutable in the commit log in the order produced.

Consumers consume events by attaching to a topic starting from the last entry or by specifying an offset. The offset is specified as a source filter "offset" on the receiver source.

## Usage

```

slim-server -d log.db -l 127.0.0.1 -p 5672 &

slim-producer -m 10 -h 127.0.0.1 -p 5672

slim-consumer -o 5 -h 127.0.0.1 -p 5672

```

## Building

Slim uses the Apache Qpid Proton Go bindings, which is a wrapper around a C library. To compile Slim, you must install the [Apache Qpid Proton](https://qpid.apache.org/proton/index.html) library. 

To pull down dependencies:

```

go get github.com/mattn/go-sqlite3

go get github.com/stretchr/testify

go get github.com/qpid-proton

```

Then, to build:

```

make

```

## TODO

* Limit log by size
