YAML-formatted and timestamped description of Function-as-a-Service (FaaS) service characteristics and constraints such as maximum execution time and pricing. This dataset allows for adaptive software and workflow generation in dynamically evolving Serverless Computing environments. We envision the inclusion of the dataset into code generators, code transformers, workflow schedulers and compatibility modes of open source FaaS runtimes. Furthermore, due to evidences of evolving values being given by hyperlinks, the dataset will serve as single source of truth about the technological development in the FaaS space.
