## Interface PartitionAttributes<K,V>

-     public interface PartitionAttributes<K,V>

  Attributes that define the partitioned character of a Partitioned Region. This interface allows for the discovery of Partitioned Region attributes using `RegionAttributes.getPartitionAttributes()` as well as the configuration of a Partitioned Region using `AttributesFactory.setPartitionAttributes(PartitionAttributes)`. PartitionAttributes are created using the `PartitionAttributesFactory` The default PartitionAttributes can be determined using `PartitionAttributesFactory.create()` with out calling any of its mutator methods e.g. `PartitionAttributesFactory.setLocalMaxMemory(int)` Also see `DataPolicy.PARTITION`.
  Since:
    GemFire 5.0

- - ### Method Detail

    - #### getRedundantCopies

          int getRedundantCopies()

      The number of Backups for an entry in PartitionedRegion. This value should be between 0 and 3 (for a total of 1 to 4 instances of the data). The default value is 0.
      Returns:
        redundantCopies.

    - #### getTotalSize

          @Deprecated
          long getTotalSize()

      Deprecated. use getTotalMaxMemory() instead
      This method returns the maximum total size of the region in megabytes.
      Returns:
        total size in megabytes.

    - #### getTotalMaxMemory

          @Deprecated
          long getTotalMaxMemory()

      Deprecated. since Geode 1.3.0
      This method returns the maximum total size of the region, in megabytes. Default value is Integer.MAX_VALUE.
      Returns:
        maximum size of the partitioned region, in megabytes

    - #### getTotalNumBuckets

          int getTotalNumBuckets()

      This method returns total number of buckets for a PartitionedRegion. Default number of buckets for a PartitionedRegion is 113.
      Returns:
        total number of buckets for a PartitionedRegion.

    - #### getLocalMaxMemory

          int getLocalMaxMemory()

      This method returns the maximum amount of local memory that can be used by the Region. By default, a PartitionedRegion can contribute 90% of the maximum memory allocated to a VM.

    - #### getColocatedWith

          java.lang.String getColocatedWith()

      Returns name of the colocated PartitionedRegion's name
      Since:
        GemFire 6.0

    - #### getLocalProperties

          @Deprecated
          java.util.Properties getLocalProperties()

      Deprecated. use `getLocalMaxMemory()` in GemFire 5.1 and later releases
      This method returns local properties. There are currently no local properties defined that are not also deprecated.
      Returns:
        localProperties

    - #### getGlobalProperties

          @Deprecated
          java.util.Properties getGlobalProperties()

      Deprecated. use `getTotalMaxMemory()` and `getTotalNumBuckets()` in GemFire 5.1 and later releases
      This method returns global properties. There are currently no global properties defined that are not also deprecated.
      Returns:
        globalProperties

    - #### getPartitionResolver

          PartitionResolver<K,V> getPartitionResolver()

      Returns the PartitionResolver set for custom partitioning
      Returns:
        `PartitionResolver` for the PartitionedRegion
      Since:
        GemFire 6.0

    - #### getRecoveryDelay

          long getRecoveryDelay()

      Returns the delay in milliseconds that existing members will wait before satisfying redundancy after another member crashes. Default value of recoveryDelay is -1 which indicates that redundancy won't be recovered if a member crashes.
      Since:
        GemFire 6.0

    - #### getStartupRecoveryDelay

          long getStartupRecoveryDelay()

      Returns the delay in milliseconds that a new member will wait before trying to satisfy redundancy of data hosted on other members. Default value is 0 which is to recover redundancy immediately when a new member is added.
      Since:
        GemFire 6.0

    - #### getPartitionListeners

          PartitionListener[] getPartitionListeners()

      Returns array of PartitionListener{s} configured on this partitioned region
      Returns:
        PartitionListener configured on this partitioned region
      Since:
        GemFire 6.5
      See Also:
        `PartitionListener`

    - #### getFixedPartitionAttributes

          java.util.List<FixedPartitionAttributes> getFixedPartitionAttributes()

      Returns `FixedPartitionAttributes`'s list of local partitions defined on this Partitioned Region
      Since:
