    Deprecated. since 6.2. Use the corresponding StatefulConnection.setTimeout(Duration) method on the connection interface. To be removed with Lettuce 7.0.
    
    Set the default timeout for operations. A zero timeout value indicates to not time out.
    
    Parameters:
    
    timeout - the timeout value
    
    Since:
    
    5.0
  - asking

    Returns:
    
    String simple-string-reply
  - auth
```
String auth(CharSequence password)

  - clusterKeyslot
```
Long clusterKeyslot(K key)
```
    Returns an integer identifying the hash slot the specified key hashes to. This command is mainly useful for debugging and testing, since it exposes via an API the underlying Redis implementation of the hashing algorithm. Basically the same as SlotHash.getSlot(byte[]).

    Returns:
    
    List<String> array-reply list of replicas. The command returns data in the same format as clusterNodes() but one line per replica.
  - clusterSlots
```
List<Object> clusterSlots()
```
    Get array of cluster slots to node mappings.
    
    Returns:
    
    List<Object> array-reply nested list of slot ranges with IP/Port mappings.
  - readOnly
```
String readOnly()
```
    Tells a Redis cluster replica node that the client is ok reading possibly stale data and is not interested in running write queries.
    
    Specified by:
    
    readOnly in interface BaseRedisCommands<K,V>
    
    Returns:
    
    String simple-string-reply
  - readWrite
```
String readWrite()
```
    Resets readOnly flag.
    
    Specified by:
    
    readWrite in interface BaseRedisCommands<K,V>
    
    Returns:
    
    String simple-string-reply
  - clusterLinks
```
List<Map<String,Object>> clusterLinks()
```
    Retrieves information about the TCP links between nodes in a Redis Cluster.
    
    Returns:
    
    List of maps containing attributes and values for each peer link.
  - getJsonParser
```
JsonParser getJsonParser()
```
    Returns:
    
    the currently configured instance of the JsonParser
    
    Since:
    
    6.5
