### Load the schema
We need to create a few tables into our new cluster. To do that, we can run the `ApplySchema` command.
```
vitess/examples/compose$ ./lvtctl.sh ApplySchema -sql "$(cat create_test_table.sql)" test_keyspace
```

### Complete starting the cluster
Now that schema has been loaded a second start will bring vtgate up as well.
```
vitess/examples/compose$ docker-compose up -d
```

### Run the client to insert and read some data
This will build and run the `client.go` file. It will insert and read data from the master and from the replica.
