Product interoperability

Can EdgeWorkers interact with metadata variables?

Yes, EdgeWorkers can read and write to PMUSER_* variables in the delivery property. See getVariable/setVariable for more information.

What product data does EdgeWorkers have access to?

EdgeWorkers has access to EdgeScape (stored in the request's User Location object) and Device Characteristics (stored in the requests's Device object).

Does EdgeWorkers replace Edge Side Includes (ESI) aka Dynamic Content Assembly (DCA)?

At some point, yes as we believe EdgeWorkers will offer a modernized approach to response and API orchestration use cases. But at the current time (2021), there are no firm plans to end of sale or end of life ESI or DCA.
