Section | [ObjectCluster] |
Abbreviation | None |
Required? | No |

Default value | None |
Usage
Specify any character string to identify the group of target tables in the cluster, or leave the value for the parameter blank. If you do not specify a value, the High-speed Apply Engine processes the cluster correctly, but the cluster is not identified in the output messages for the request.
You can specify as many clusters as you need to distribute the workload for the apply request. You define a table as a member of a cluster by using the Table parameter, as described in Table. A cluster includes all of the Table parameters that follow it until another Cluster parameter is specified. Each Cluster parameter indicates the start of a new object cluster.
High-speed Apply Engine groups all of the tables defined for a cluster to be processed by a single agent. When you define clusters, consider the amount of work required for the target tables. If you group large tables or tables that require large numbers of updates, you can negatively impact the performance of the High-speed Apply Engine.
