# Configuring timeouts in the Elasticsearch Java REST 5 client
You can set timeouts when building the `Rest5Client`:
- The **connect timeout** is the maximum time for establishing a TCP connection, including the TLS handshake. The connect timeout is set on `ConnectionConfig`.
- The **socket timeout** is the maximum time to wait for I/O on an established socket. The socket timeout is set on `ConnectionConfig`.
- The **response timeout** is the maximum period to wait for response data. The response timeout is set on `RequestConfig`.
- The **connection request timeout** is the maximum time for leasing a connection from the pool. The connection request timeout is set on `RequestConfig`.

To configure timeouts, use `setConnectionConfigCallback` and `setRequestConfigCallback` while building the `Rest5Client`. The following example sets a 10-second connect timeout, a 10-second socket timeout, and a 20-second response timeout:
```java
Rest5ClientBuilder builder = Rest5Client
    .builder(new HttpHost("http", "localhost", 9200)) 
    .setConnectionConfigCallback(connectConf -> connectConf
        .setConnectTimeout(Timeout.ofSeconds(10))
        .setSocketTimeout(Timeout.ofSeconds(10)))
    .setRequestConfigCallback(r -> r
        .setResponseTimeout(Timeout.ofSeconds(20))
    );
```

You can also set per-request timeouts using `RequestOptions`, which override the builder defaults. The following example sets a response timeout of 60 seconds, as well as a connection request timeout of 1 second (to limit pooled connection wait time):
```java
RequestConfig requestConfig = RequestConfig.custom()   
    .setResponseTimeout(Timeout.ofSeconds(60))
    .setConnectionRequestTimeout(Timeout.ofSeconds(1))
    .build();

RequestOptions options = RequestOptions.DEFAULT.toBuilder()
    .setRequestConfig(requestConfig)
    .build();

ElasticsearchTransport transport = new Rest5ClientTransport(
    restClient, new JacksonJsonpMapper(), options);
```
