    • getName

      public String getName()
      Gets the name of the executor task.
      Specified by:
      getName in interface NamedConfig
      Returns:
      the name of the executor task

    • setName

      public ScheduledExecutorConfig setName(String name)
      Sets the name of the executor task.
      Specified by:
      setName in interface NamedConfig
      Parameters:
      name - the name of the executor task
      Returns:
      this executor config instance

    • getPoolSize

      public int getPoolSize()
      Gets the number of executor threads per member for the executor.
      Returns:
      the number of executor threads per member for the executor

    • setPoolSize

      public ScheduledExecutorConfig setPoolSize(int poolSize)
      Sets the number of executor threads per member for the executor.
      Parameters:
      poolSize - the number of executor threads per member for the executor

    • getDurability

      public int getDurability()
      Gets the durability of the executor
      Returns:
      the durability of the executor

    • setDurability

      public ScheduledExecutorConfig setDurability(int durability)
      Sets the durability of the executor The durability represents the number of replicas that exist in a cluster for any given partition-owned task. If this is set to 0 then there is only 1 copy of the task in the cluster, meaning that if the partition owning it, goes down then the task is lost.
      Parameters:
      durability - the durability of the executor
      Returns:
      this executor config instance

    • getCapacity

      public int getCapacity()
      Gets the capacity of the executor
      Returns:
      the capacity of the executor

    • setCapacity

      public ScheduledExecutorConfig setCapacity(int capacity)
      Sets the capacity of the executor The capacity represents the maximum number of tasks that a scheduler can have at any given point in time per partition or per node according to the capacity policy. If this is set to 0 then there is no limit To prevent any undesirable data-loss, capacity is ignored during partition migrations, the count is updated accordingly, however the rejection is not enforced.
      Parameters:
      capacity - the capacity of the executor
      Returns:
      this executor config instance

    • getCapacityPolicy

      public ScheduledExecutorConfig.CapacityPolicy getCapacityPolicy()
      Returns:
      the policy of the capacity setting

    • setCapacityPolicy

      public ScheduledExecutorConfig setCapacityPolicy(@Nonnull ScheduledExecutorConfig.CapacityPolicy capacityPolicy)
      Set the capacity policy for the configured capacity value To prevent any undesirable data-loss, capacity is ignored during partition migrations, the count is updated accordingly, however the rejection is not enforced.
      Parameters:
      capacityPolicy -

    • getSplitBrainProtectionName

      public String getSplitBrainProtectionName()
      Returns the split brain protection name for operations.
      Returns:
      the split brain protection name

    • setSplitBrainProtectionName

      public ScheduledExecutorConfig setSplitBrainProtectionName(String splitBrainProtectionName)
      Sets the split brain protection name for operations.
      Parameters:
      splitBrainProtectionName - the split brain protection name
      Returns:
      the updated configuration

    • getMergePolicyConfig

      public MergePolicyConfig getMergePolicyConfig()
