RE: [tosca] key_schema in TOSCA 1.3?

[Chris Lauwers <lauwers@ubicity.com>]

As a compromise, perhaps we can restrict key_schema to only allow scalar types (or types that derive from scalar types).

I would like to ask the group to reconsider the new "key_schema" feature.

 

While it's true that complex keys are supported in YAML, hashtables with complex keys are not widely supported across programming languages, data formats (JSON), databases (relational, graph), memory caches, etc.

 

In working to implement this feature in Puccini I am hitting many problems that would require adding workarounds with considerable complexity, in particular in its interfaces with the orchestration systems it supports.

 

My guess is that it was added to provide some grammatical completeness, but I would like to re-discuss its practicality and necessity. Can we add this to the meeting agenda?
