  • Method Details

    • getPolicy

      public String getPolicy()
      Returns the classname of the SplitBrainMergePolicy.
      Returns:
      the classname of the merge policy

    • setPolicy

      public MergePolicyConfig setPolicy(String policy)
      Sets the classname of your SplitBrainMergePolicy.

      For the out-of-the-box merge policies the simple classname is sufficient, e.g. PutIfAbsentMergePolicy. But also the fully qualified classname is fine, e.g. com.hazelcast.spi.merge.PutIfAbsentMergePolicy. For a custom merge policy the fully qualified classname is needed.

      Must be a non-empty string. The default value is PutIfAbsentMergePolicy.

      Parameters:
      policy - the classname of the merge policy
      Returns:
      this MergePolicyConfig instance

    • getBatchSize

      public int getBatchSize()
      Returns the batch size, which will be used to determine the number of entries to be sent in a merge operation.
      Returns:
      the batch size

    • setBatchSize

      public MergePolicyConfig setBatchSize(int batchSize)
      Sets the batch size, which will be used to determine the number of entries to be sent in a merge operation.

      Must be a positive number. Set to 1 to disable batching. The default value is 100.

      Parameters:
      batchSize - the batch size
      Returns:
      this MergePolicyConfig instance
