The LDTM logs the results of the Spark engines execution plan run for the mapping. You can view the LDTM log from the Developer tool or the Monitoring tool for a mapping job. The log for the Spark engine shows the step to translate the mapping to an internal format, steps to optimize the mapping, steps to render the mapping to Spark code, and the steps to submit the code to the Spark executor. The logs also show the Scala code that the Logical Data Translation Generator creates from the mapping logic.
