Partitioning Options Settings

Partitioning Options Settings

When you configure dynamic partitioning, the Integration Service determines the number of partitions to create at run time. Configure dynamic partitioning on the Config Object tab of session properties.
The following table describes the Partitioning Options settings on the Config Object tab:
Partitioning Options Settings
Description
Dynamic Partitioning
Configure dynamic partitioning using one of the following methods:
  • Disabled. Do not use dynamic partitioning. Define the number of partitions on the Mapping tab.
  • Based on number of partitions. Sets the partitions to a number that you define in the Number of Partitions attribute. Use the $DynamicPartitionCount session parameter, or enter a number greater than 1.
  • Based on number of nodes in grid. Sets the partitions to the number of nodes in the grid running the session. If you configure this option for sessions that do not run on a grid, the session runs in one partition and logs a message in the session log.
  • Based on source partitioning. Determines the number of partitions using database partition information. The number of partitions is the maximum of the number of partitions at the source.
  • Based on number of CPUs. Sets the number of partitions equal to the number of CPUs on the node that prepares the session. If the session is configured to run on a grid, dynamic partitioning sets the number of partitions equal to the number of CPUs on the node that prepares the session multiplied by the number of nodes in the grid.
Default is disabled.
Number of Partitions
Determines the number of partitions that the Integration Service creates when you configure dynamic partitioning based on the number of partitions. Enter a value greater than 1 or use the $DynamicPartitionCount session parameter.
