Srikanth Sundarrajan commented on FALCON-2182:
----------------------------------------------
Thanks [~pallavi.rao]. Have a few questions on the design proposal.
1. Noted that the User Parameter Template returns a collection of properties. Is this fixed
to be a collection of properties ? If it merely a illustrative example and is not meant to
be a collection of properties then it looks alright. There may be issues in fixing this to
be a collection of properties, as it may be restrictive.
2. Why is preparation & submission separated out ? This might lead to users tampering
with the output of the prepared entities and may produce undesirable results. It might be
better to keep them locked down IMHO. I can see the need for some parameterization, which
can be supported through config overlays.
3. Can extensions be removed while being referred to ? I am guessing it should have an option
to be disabled without being removed. As documentation will go missing if removed completely.
4. Are we thinking of extensions as a convenient way for generating entities or are we thinking
of extensions as a atomic unit of reusable functionality? In other words, Is extensions role
is to only generate the entities and from there on we simply allow the processes & feeds
created to be managed individually or Are we looking at them as a functional capability and
the parts that make them (collection of processes & feeds) are inseparable ?

> Currently server-side trusted extensions are supported (see FALCON-634 for more details).
> Need to extend the Falcon Extensions to support extensions built by users. For example,
lets say a user wants to add an extension for "data-quality check". This shouldn't require
it to be compiled and tested with Falcon build. User should be able to add it on-the-fly (while
the Falcon Server is running) and other users should be able to discover it, and "instantiate"
this new extension.
