# Groupcache DB Experiment - Revisited 2019

This is the second revision of Capotej's [Groupcache DB Experiment](https://github.com/capotej/groupcache-db-experiment).

I decided to replay again his experiment using newer techniques, such the use of go mod, protobuf and error wrapping.

This project simulates a scenario wherein a few frontends running [groupcache](http://github.com/golang/groupcache) are fronting a slow database. See his [blog post](http://capotej.com/blog/2013/07/28/playing-with-groupcache/) about it for more details.

# Getting it running

The following commands will set up this topology:

![groupcache topology](https://raw.github.com/cirello-io/groupcache-experiment/master/topology.png)

### Build everything

1. ```git clone https://github.com/cirello-io/groupcache-experiment.git```

3. ```go build ./cmd/backend```

4. ```go build ./cmd/frontend```

5. ```go build ./cmd/cli```

### Start DB server

1. ```./backend```

This starts a deliberately slow k/v datastore on :8080

### Start Multiple Frontends

1. ```./frontend -listen "http://localhost:8001" -frontend "localhost:9001" ```

2. ```./frontend -listen "http://localhost:8002" -frontend "localhost:9002" ```

3. ```./frontend -listen "http://localhost:8003" -frontend "localhost:9003" ```

### Use the CLI to set/get values

1. ```./cli -set -k foo -v bar```

2. ```./cli -get -k foo``` should see bar in 300 ms

3. ```./cli -get -k foo``` should see bar instantly
