# Cassandra Golang Example

This repository shows basic Cassandra CRUD operations using Golang.

## Overview

We will create a keyspace according to the `scripts/cassandra.cql`:

```

CREATE KEYSPACE roster WITH replication = {'class': 'SimpleStrategy', 'replication_factor' : 1};

USE roster;

CREATE TABLE employees (

    id UUID,

    firstname varchar,

    lastname varchar,

    age int,

    PRIMARY KEY(id)

);

CREATE INDEX ON employees(age);

CREATE TABLE messages (

    channel UUID,

    msg_id int,

    username varchar,

    content text,

    PRIMARY KEY((channel), msg_id, username)

) WITH CLUSTERING ORDER BY (msg_id DESC);

```

The keyspace will be created in Cassandra on startup. Note that we have created an index on `age` field so that we could query by `age` besides primary key.

## Usage

```bash

docker-compose up

```
