Mapping data often requires casting data types into Boolean. Often, a system provides binary signals as 0s and 1s. However, a different application might require the same data in Boolean (true/false). In these cases, the Cast: Boolean mapper is utilized.
Here’s how you can do it!
Step 1: Click on Add Data Transformer.
Step 2: Select Value Mapper.
Step 3: Select Key Accessor from the Accessor drop-down menu.
Step 4: Click on Add Keys and specify the key (or keys) that you want to map.
Step 5: Click on Add Mappers and select Cast: Boolean
Step 6: On clicking the Run Test button, you will see that the Cast: Boolean mapper has mapped the specified key (must be in 0s and 1s) to true/false accordingly.
