public boolean mutationTokensEnabled()
```
    Description copied from interface: CoreEnvironment
    
    Returns true if extended mutation tokens are enabled.
    Note that while this may return true, the server also needs to support it (Couchbase Server 4.0 and above). It will be negotiated during connection setup, but needs to be explicitly enabled on the environment as well to take effect (since it has a 16 bytes overhead on every mutation performed).
    
    Specified by:
    
    mutationTokensEnabled in interface CoreEnvironment
    
    Returns:
    
    true if enabled on the client side.

    the socket connect timeout in milliseconds.
  - callbacksOnIoPool
```
public boolean callbacksOnIoPool()
```
    Description copied from interface: CoreEnvironment
    
    Returns true if the Observable callbacks are completed on the IO event loops.
    Note: this is an advanced option and must be used with care. It can be used to improve performance since it removes additional scheduling overhead on the response path, but any blocking calls in the callbacks will lead to more work on the event loops itself and eventually stall them.
    
    Specified by:
    
    callbacksOnIoPool in interface CoreEnvironment
    
    Returns:
    
    true if callbacks are scheduled on the IO event loops.

    Specified by:
    
    memcachedHashingStrategy in interface ConfigParserEnvironment
    
    Returns:
    
    the memcached hashing strategy.
