Set the Number of Redundant Copies

Configure in-memory high availability for your partitioned region by specifying the number of secondary copies you want to maintain in the region's data stores.

Specify the number of redundant copies you want for your partitioned region data in the partition attribute redundant-copies setting. The default setting is 0.
For example:
  • XML:
    <region name="PR1"> 
      <region-attributes refid="PARTITION"> 
        <partition-attributes redundant-copies="1"/> 
  • Java:
    PartitionAttributes pa = 
        new PartitionAttributesFactory().setRedundantCopies(1).create();
