Welcome to where the magic (Functions) happens. Some argue that the magic of Stream lies in avoiding vendor lock-in by supporting myriad Sources and Destinations allowing you to connect almost anything to anything. They are also right. But we're here to talk about Functions.

A Function is code that transforms the data inside an event. It can:

• Extract (and label) information from a payload for later use
• Delete erroneous data from an event
• Add important information to an event
• Edit data inside an event to help you better understand it
• Mask sensitive data inside of payloads to ensure no accidental exposure of personal identifiable information (PII) down the line
• Many more!
