Optimizer Levels

Optimizer Levels

Effective in version 10.2.2, you can configure the Auto optimizer level for mappings and mapping tasks. With the Auto optimization level, the Data Integration Service applies optimizations based on the execution mode and mapping contents.
The optimizer level default for new mappings is Auto.
When you upgrade to version 10.2.2, optimizer levels configured in mappings remain the same. To use the Auto optimizer level with upgraded mappings, you must manually change the optimizer level.
For more information, see the "Optimizer Levels" chapter in the
Informatica 10.2.2 Developer Mapping Guide
