This step extracts records from a data source. The output endpoint out_extract contains records satisfying the specified condition. The output endpoint out contains all records.

Because this step is internally implemented via a filter, it allows usage of whenCondition. If this condition is used it will cause non-passing records to be excluded from the step processing. Such records are copied directly to the output, without affecting the out_extract endpoint.

To ensure that all records are processed, the whenCondition should not be used in this step.
