ISW - Wizard: Create New Stream

[grotlue]

• As part of the "Setup Routing" step
• Shows a form to create a new stream with:
  • Title
  • Description (optional)
  • Index Set (select of existing index sets), refreshes regularly
    • only user-created ones (no illuminate or System Messages)
  • Checkbox: Remove matches from Default Stream
  • Checkbox: Create a new Pipeline for this Stream
  • Select of all existing pipelines (only one can be selected)
• Shows a button "Create a New Index Set", on click
  • Opens the existing index set creation form in a new tab
• Shows a button "All Done - Start Input" which leads to ISW - Wizard Step: Start Input Step #20567
• The stream is not created at this point, but all the configuration will be set

@tellistone If the user chooses to "Create a new Pipeline for this Stream" what exactly is the content of the pipeline? Is it just an "empty" one with a name?

[grotlue]

APIs:

• http://localhost:8080/api/api-browser/global/index.html#!/Streams/create_post_1 to create a new stream
• http://localhost:8080/api/api-browser/global/index.html#!/System/IndexSets/list_get_0 to list all index sets

Yes - empty pipeline with name that corresponds to the new stream, attached to the new stream

[grotlue]

Added backend label as we need to routes the messages to the new stream

[grotlue]

@tellistone Do I understand correctly that we want to ask the user if they want to create another custom stream?

[tellistone]

Yeah, their options are

1. no routing, same as today
2. pick an existing stream, we create routing to it
3. create a new stream, optionally attach an existing pipeline to it, create routing to it

[tellistone]

In ui design, we should push the "Create a New Index Set" action as highly recommended.

[grotlue]

For the contextual warning in the mockup there is no API. At least I couldn't find one that returns a list of streams connected to a specific index set. @patrickmann correct me if I'm wrong. I'd suggest to continue with this issue without that and if we want to have it, create a seperate one.

[patrickmann]

The stream APIs do include information about index sets. To find all streams for a specific index set, you currently have to call GET /streams and then filter by the desired index set.

The BE already has a method indexSetIdsByIds to return all stream IDs for a given set of index IDs, but it is not exposed as an API.

[grotlue]

I think it would be a better solution if we can either can integrate the streams in the index sets list call or add a new call to get all streams for one index set (id).
I don't think it makes a lot of sense to get the whole stream list only for that use case.
