Trace for general data

The trace file records map execution progress. You can enable the trace option from the map settings or from the adapter command line. You can trace the input data, the output data, or both.

An input data trace file includes a message for each input data object. The trace file contains the sizes and counts of data objects, and the data object position in the data stream. If the data object is invalid, the trace file includes the reason the data is invalid.

Static input files produce a trace file only if the static input fails validation when the map loads. A map trace file describes a valid static input as a reused work file.

When output data is traced, the trace file specifies the objects that are built and the output objects that evaluate to none.

Because performance can be impacted, enable the trace option only during debugging.
