Resource Naming

Amazon State Language specifies that "Resource field" MUST be a URI.

A Task State MUST include a “Resource” field, whose value MUST be
a URI that uniquely identifies the specific task to execute. The
States language does not constrain the URI scheme nor any other
part of the URI.

Function

FaaS Shell looks up the following information form the "Resource field", and dispatch the function invocation to an appropriate FaaS vendor plug-in.

  • Beginning with a lower-case letter indicates literal.
  • Beginning with an upper-case letter indicates variable.
  • ':' indicates a separator.
  • '_' indicates an arbitrary value, that is ignored.
