## Interface ClientCompute

-     public interface ClientCompute

  Thin client compute facade. Defines compute grid functionality for executing tasks over nodes in the `ClientClusterGroup`

- - ### Method Summary

    All Methods Instance Methods Abstract Methods Deprecated Methods
    Modifier and Type | Method and Description
    --- | ---
    `ClientClusterGroup` | `clusterGroup()` Gets cluster group to which this `ClientCompute` instance belongs.
    `<T,R> R` | `execute(String taskName, T arg)` Executes given task within the cluster group.
    `<T,R> Future<R>` | `executeAsync(String taskName, T arg)` Deprecated. Use `executeAsync2(String, Object)` instead. This method calls `executeAsync2(String, Object)` internally, but returns a more limited Future interface.
    `<T,R> IgniteClientFuture<R>` | `executeAsync2(String taskName, T arg)` Executes given task asynchronously within the cluster group.
    `ClientCompute` | `withNoFailover()` Sets no-failover flag for tasks executed by returned `ClientCompute` instance.
    `ClientCompute` | `withNoResultCache()` Disables result caching for tasks executed by returned `ClientCompute` instance.
    `ClientCompute` | `withTimeout(long timeout)` Sets timeout for tasks executed by returned `ClientCompute` instance.

- - ### Method Detail

    - #### clusterGroup

          ClientClusterGroup clusterGroup()

      Gets cluster group to which this `ClientCompute` instance belongs.
      Returns:
        Cluster group to which this `ClientCompute` instance belongs.

    - #### execute

          <T,R> R execute(String taskName,
                          @Nullable
                          T arg)
                   throws ClientException,
                          InterruptedException

      Executes given task within the cluster group. For step-by-step explanation of task execution process refer to `ComputeTask` documentation.
      Parameters:
        `taskName` - Name of the task to execute.
        `arg` - Optional argument of task execution, can be `null`.
      Returns:
        Task result.
      Throws:
        `ClientException` - If task failed.
        `InterruptedException` - If the wait for task completion was interrupted.
      See Also:
        `for information about task execution.`

    - #### executeAsync

          @Deprecated
          <T,R> Future<R> executeAsync(String taskName,
                                                   @Nullable
                                                   T arg)
                                            throws ClientException

      Deprecated. Use `executeAsync2(String, Object)` instead. This method calls `executeAsync2(String, Object)` internally, but returns a more limited Future interface.
      Executes given task asynchronously within the cluster group. For step-by-step explanation of task execution process refer to `ComputeTask` documentation.
      Parameters:
        `taskName` - Name of the task to execute.
        `arg` - Optional argument of task execution, can be `null`.
      Returns:
        A Future representing pending completion of the task.
      Throws:
        `ClientException` - If task failed.
      See Also:
        `for information about task execution.`

    - #### executeAsync2

          <T,R> IgniteClientFuture<R> executeAsync2(String taskName,
                                                    @Nullable
                                                    T arg)
                                             throws ClientException

      Executes given task asynchronously within the cluster group. For step-by-step explanation of task execution process refer to `ComputeTask` documentation.
      Parameters:
        `taskName` - Name of the task to execute.
        `arg` - Optional argument of task execution, can be `null`.
      Returns:
        A Future representing pending completion of the task.
      Throws:
        `ClientException` - If task failed.
      See Also:
        `for information about task execution.`

    - #### withTimeout

          ClientCompute withTimeout(long timeout)

      Sets timeout for tasks executed by returned `ClientCompute` instance.
      Returns:
        `ClientCompute` instance with given timeout.

    - #### withNoFailover

          ClientCompute withNoFailover()

      Sets no-failover flag for tasks executed by returned `ClientCompute` instance. If flag is set, job will be never failed over even if remote node crashes or rejects execution. See `ComputeTask` documentation for more information about jobs failover.
      Returns:
        `ClientCompute` instance with no-failover flag.

    - #### withNoResultCache

          ClientCompute withNoResultCache()

      Disables result caching for tasks executed by returned `ClientCompute` instance. See `ComputeTask` documentation for more information tasks result caching.
      Returns:
        `ClientCompute` instance with "no result cache" flag.
