IBM InfoSphere Datastage - Difference between Compile and Force Compile

Force Compile will force each and every peach of code to be rebuild even though code is being re-compiled with minor changes.

Compile will try to optimize the process and will be faster than force compile. Because Compile process will check for difference between the new version and old version, and rebuild only the changes in the code.

Consider using Force Compile if the job has transformer change. Because the external factors like environment variable APT_TRANSFORM_OPERATOR_DEBUG will impact how transformation stages are compiled in terms of preserving transformer code and reporting compilation.
