> Rest APIs to render the Designer UI
> -----------------------------------

> Key: FALCON-387
> URL: https://issues.apache.org/jira/browse/FALCON-387
> Project: Falcon
> Issue Type: Sub-task
> Reporter: samar
> Attachments: FALCON-322_1.patch
>
>
> We need CRUD apis for FLOWS
> Each flow would contain a list of transformations
> We need a rest api to get the list of transformation (to start with it would
> return a static list of transformation)
> Each transformation need to be mapped to a UI element for a custom view
> We need a rest api to get the list of actions
> After the creation of flow(sequence of transformation applied to a feed) ,
> flow object should be serialised on the GWT end and send to
> FalconDesignerRestServer to compile
> A concrete implementation of a configuration object would exist per
> transformation. The configuration object will help us populate the UI elements
> FalconDesignerRestServer will expose a rest api to compile which will return
> success or errors
> FalconDesignerRestServer also need to expose a rest api to deploy the flow
> Flows will be saved as different version.
> Flows are organised under folders(UI representation). It can be passed as
> another property e.g. group=analytics.
> Action items
> Create a rest App(FalconDesignerRestServer)
> Expose following APIs
> expose CRUD apis for FLOWS
> getFlow() api should pass a version . if no versions is passed then the
> default(latest version) should be returned.
> list all transformations
> Creating UI elements per transformation/action and store the mapping of
> transformation to the related UI element.
> list all Actions
> compile a flow
> provision a flow
> Methods to
> Serialise a flow. Which would internally serialze the list of transformations
> To start with we will create dummy rest apis to unblock UI development
