## Isolation Pool
[TODO](./blocking-commands.md).
In v4, `RedisClient` had the ability to create a pool of connections using an "Isolation Pool" on top of the "main" connection. However, there was no way to use the pool without a "main" connection:
```javascript
await client.get(client.commandOptions({ isolated: true }), 'key');
const client = await createClient()
.on('error', err => console.error(err))
.connect();
await client.ping(
client.commandOptions({ isolated: true })
);
```
```javascript
await client.sendCommand(['GET', 'key']);
const pool = client.createPool({
min: 0,
max: Infinity
});
await pool.blPop('key');
await pool.sendCommand(['GET', 'key']);
await pool.use(client => client.blPop());
In v5 we've extracted this pool logic into its own class—`RedisClientPool`:
await cluster.sendCommand('key', true, ['GET', 'key']);
const clusterPool = cluster.createPool({
min: 0,
max: Infinity
});
await clusterPool.blPop('key');
await clusterPool.sendCommand('key', true, ['GET', 'key']);
await clusterPool.use(client => client.blPop());
```javascript
const pool = await createClientPool()
.on('error', err => console.error(err))
.connect();
await pool.ping();
```
See the [pool guide](./pool.md) for more information.
## Cluster `MULTI`
In v4, `cluster.multi()` did not support executing commands on replicas, even if they were readonly.

### Connection State
To client exposes 2 `boolean`s that track the client state:
1. `isOpen` - the client is either connecting or connected.
2. `isReady` - the client is connected and ready to send
### Redis Commands
There is built-in support for all of the [out-of-the-box Redis commands](https://redis.io/commands). They are exposed using the raw Redis command names (`HSET`, `HGETALL`, etc.) and a friendlier camel-cased version (`hSet`, `hGetAll`, etc.):
