## how to run local development

### single node cluster

- run scylladb locally:

```

docker run --name scylla-node1 --hostname scylla-node1 -d scylladb/scylla

docker exec -it scylla-node1 nodetool status 

```

- create a keyspace (configurate with 1 node):

```sql

docker exec -it scylla-node1 cqlsh [node address from nodetool status]

cqlsh> CREATE KEYSPACE mykeyspace WITH REPLICATION = { 'class' : 'NetworkTopologyStrategy', 'replication_factor' : 1};

```

### multi node cluster

- run scylladb locally:

```

docker-compose up -d

docker exec -it scylla-node1 nodetool status 

```

- create a keyspace (configurate with 3 node):

```sql

docker exec -it scylla-node1 cqlsh 172.21.0.2

cqlsh> CREATE KEYSPACE mykeyspace WITH REPLICATION = { 'class' : 'NetworkTopologyStrategy', 'replication_factor' : 2};

```

### seed example data

- pre-populate some data:

```sql

use mykeyspace;

CREATE TABLE users ( user_id int, fname text, lname text, PRIMARY KEY((user_id)));

insert into users(user_id, fname, lname) values (1, 'rick', 'sanchez');

insert into users(user_id, fname, lname) values (4, 'rust', 'cohle');

select * from users;

```

switch consistency modes: 

```ts

docker exec -it scylla-node1 cqlsh 172.21.0.2

cqlsh>CONSISTENCY QUORUM // most of the nodes should respond else failed

cqlsh>CONSISTENCY ALL // all of the nodes should respond else failed

cqlsh>CONSISTENCY ANY // at least 1 of the nodes should respond else failed

cqlsh>CONSISTENCY ONE // one of the nodes should respond else failed

```

- create .env file and fill proper parameters of db connection DB_CONN_STRING=127.0.0.1 and DB_KEY_SPACE=mykeyspace

- run application

```

make start

```

- run tests

```

make test

```
