Click on the Create button on the top-right corner.
Then select the Transformation Flow option.
You will be taken to the transformation builder.
Hover your cursor over the Input Steps button on the left side to make the panel appear. (Click here to learn more about each of these input steps.)
Then drag an input step from this panel onto the canvas. (For this procedure, we will use the single database table as an example. Click here to learn about the different input steps.)
On doing so, a popup will appear, requiring information on the selected data source. (The steps within this popup will differ for each type of input step.)
Select the data source, and then a single table (since our selected input was a single table).
Then click on the Submit button.
Next, click on the newly created input step in the canvas. Its details will appear in the configure flow panel.
Note: Clicking on a blank space in the canvas will show the configurations of the entire flow, but clicking on a specific step shows only that step’s configurations.
If required, you can rename the input step. Click on the Details tab in the Configuration panel, and provide a new name, or even an updated description.
Click on the Configure tab and select only the fields that you want data to be extracted from.
Click on the Add Filter button to apply filters to control the data being extracted, when the Filter popup appears.
Once you’re done with the configuration, click on the Apply button.
Warning
You must click on the Apply button to save the configuration details. If you do not click on this button, and click anywhere else first, you will lose the config details.
On doing so, the data preview panel will display the data extracted from the configured data source. A maximum row setting of 200 applies.
You can apply transformations to fields directly from the data panel. Click here to learn more.
A new Fields tab will also appear in the Configuration panel. Use this to manage the data fields that are extracted.
