      config

    • getNettyThreads

      public int getNettyThreads()

    • getNettyExecutor

      public Executor getNettyExecutor()

    • setNettyExecutor

      public Config setNettyExecutor(Executor nettyExecutor)
      Use external Executor for Netty.

      For example, it allows to define Executors.newVirtualThreadPerTaskExecutor() to use virtual threads.

      The caller is responsible for closing the Executor.

      Parameters:
      nettyExecutor - netty executor object
      Returns:
      config

    • setExecutor

      public Config setExecutor(ExecutorService executor)
      Use external ExecutorService. ExecutorService processes all listeners of RTopic, RPatternTopic RRemoteService invocation handlers and RExecutorService tasks.

      The caller is responsible for closing the ExecutorService.

      Parameters:
      executor - object
      Returns:

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

      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
