Map input/output data

This page provides examples of input and output data in the Map function, taken from the example stream Data Enrichment With Foreign Exchange Rates. These views can help you troubleshoot and validate that the function works as intended.

Here are some example streams that use the Map function. These pre-configured streams can be found and executed from the UsageCloud platform for further learning. See https://infozone.atlassian.net/wiki/x/rMB3 for more details.
