----------------------------
Summary: 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
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
