Let's do some testing and explore the results:
hello_world
transformation. 10
to 1000
so that it generates 1,000 rows.You did some tests with the hello_world
transformation and saw the results in the Execution Results window.
The Execution Results window shows you what is happening while you preview or run a transformation.
The Logging tab shows the execution of your transformation, step by step. By default, the level of the logging detail is Basic but you can change it to see different levels of detail—from a minimal logging (level Minimal) to a very detailed one (level RowLevel).
The Step Metrics tab shows, for each step of the transformation, the executed operations and several status and information columns. You may be interested in the following columns:
Column |
Description |
---|---|
Read |
Contains the number of rows coming from previous steps |
Written |
Contains the number of rows leaving from this step toward the next |
Input |
Number of rows read from a file or table |
Output |
Number of rows written to a file or table |
Errors |
Errors in the execution. If there are errors, the whole row becomes red |
Active |
Tells the current status of the execution |
In the example, you can see that the Generate Rows step writes rows, which then are read by the Dummy step. The Dummy step also writes the same rows, but in this case those go nowhere.
For each of the following, decide if the sentence is true or false:
