## Examples

```
application start.
 eredis_pool:start().
 ok
```

key-value set and get
```
 eredis_pool:q({global, dbsrv}, ["SET", "foo", "bar"]).
 {ok,<<"OK">>}

 eredis_pool:q({global, dbsrv}, ["GET", "foo"]).
 {ok,<<"bar">>}
```

Redis Pipeline
```
 Pipeline = [["SET", a, "1"],
      ["LPUSH", b, "3"],
      ["LPUSH", b, "2"]].
 eredis_pool:qp({global,dbsrv}, Pipeline).
```

create new pool with default settings.
```
 eredis_pool:create_pool(pool1, 10).
 {ok,<0.64.0>}
```

and omissible argments(host, port, database, password reconnect_sleep).
```
 eredis_pool:create_pool(pool1, 10, "127.0.0.1", 6379, 1, "abc", 100).
 {ok,<0.64.0>}
```

using new pool
```
 eredis_pool:q(pool1, ["GET", "foo"]).
 {ok,<<"bar">>}
```
