```
public Config setExecutor(ExecutorService executor)
```
    Use external ExecutorService. ExecutorService processes all listeners of RTopic, RRemoteService invocation handlers and RExecutorService tasks.
    The caller is responsible for closing the ExecutorService.
    
    Parameters:
    
    executor - object
    
    Returns:
    
    config

  - setEventLoopGroup
```
public Config setEventLoopGroup(io.netty.channel.EventLoopGroup eventLoopGroup)
```
    Use external EventLoopGroup. EventLoopGroup processes all Netty connection tied to Redis servers. Each EventLoopGroup creates own threads and each Redisson client creates own EventLoopGroup by default. So if there are multiple Redisson instances in same JVM it would be useful to share one EventLoopGroup among them.
    Only EpollEventLoopGroup, KQueueEventLoopGroup NioEventLoopGroup can be used.
    The caller is responsible for closing the EventLoopGroup.
    
    Parameters:
    
    eventLoopGroup - object
    
    Returns:
    
    config
  - getEventLoopGroup
```
public io.netty.channel.EventLoopGroup getEventLoopGroup()
```
  - setLockWatchdogTimeout
```
public Config setLockWatchdogTimeout(long lockWatchdogTimeout)
```
    This parameter is only used if lock has been acquired without leaseTimeout parameter definition. Lock will be expired after lockWatchdogTimeout if watchdog didn't extend it to next lockWatchdogTimeout time interval.
    This prevents against infinity locked locks due to Redisson client crush or any other reason when lock can't be released in proper way.
    Default is 30000 milliseconds
    
    Parameters:
    
    lockWatchdogTimeout - timeout in milliseconds
    
    Returns:
    
    config
  - getLockWatchdogTimeout
```
public long getLockWatchdogTimeout()
```
  - setKeepPubSubOrder
```
public Config setKeepPubSubOrder(boolean keepPubSubOrder)
```
    Defines whether to keep PubSub messages handling in arrival order or handle messages concurrently.
    This setting applied only for PubSub messages per channel.
    Default is true.
    
    Parameters:
    
    keepPubSubOrder - - true if order required, false otherwise.
    
    Returns:
    
    config
  - isKeepPubSubOrder
```
public boolean isKeepPubSubOrder()
```
  - setAddressResolverGroupFactory
```
public Config setAddressResolverGroupFactory(AddressResolverGroupFactory addressResolverGroupFactory)
```

    Parameters:
    
    addressResolverGroupFactory -
    
    Returns:
    
    config
  - getAddressResolverGroupFactory
```
public AddressResolverGroupFactory getAddressResolverGroupFactory()
```

  - setUseScriptCache
```
public Config setUseScriptCache(boolean useScriptCache)
```
    Defines whether to use Lua-script cache on Redis side. Most Redisson methods are Lua-script based and this setting turned on could increase speed of such methods execution and save network traffic.
    NOTE: readMode option is not taken into account for such calls as Redis slave redirects execution of cached Lua-script on Redis master node.
    Default is false.
    
    Parameters:
    
    useScriptCache - - true if Lua-script caching is required, false otherwise.
    
    Returns:
    
    config
  - isUseScriptCache

```
public Config setDecodeInExecutor(boolean decodeInExecutor)
```
    Defines whether to decode data by codec in executor's threads or netty's threads. If decoding data process takes long time and netty thread is used then `RedisTimeoutException` could arise time to time.
    Default is false.
    
    Parameters:
    
    decodeInExecutor - - true to use executor's threads, false to use netty's threads.
    
    Returns:
