You can use the Informatica Connector Toolkit to specify the partition type and implement the partition logic to use when the adapter reads or writes data.
Based on the partition logic you implement for an adapter, the Data Integration Service dynamically divides the underlying data into partitions and processes all of the partitions concurrently.
You can specify the following partitioning types for an adapter:
A partitioning logic that determines the number of partitions at run time based on the partition information from the data source. If the data source provides partition information, you can use dynamic partitioning to increase the performance of adapter read and write operations.
A partitioning logic that is based on the partition information that the user specifies, such as number of partitions or key range. If you require the user to specify the partition information, you can implement fixed partitioning for the adapter. If the tables in the data source support key range partitioning, you can add key range partitioning capability for the adapter.
