[Feature Request] Standardize method for listing workflow queries/signals (and maybe other things like registered activities/workflows and other metadata) #51
Description
Up until now we've used a hack to get the list of registered queries from a workflow execution.
The hack is to send a query to a workflow, which responds with something like "query not found, list of registered queries...", parse the response and show in the UI.
A standard way to support listing workflow queries would be to have a "listQueries" (name TBD) built-in query provided by the Workflow runtime.
We'd have to keep the hack around to support SDKs that still do not support the listQueries built-in query (all at the time of this writing).
UPDATE: Here is the roadmap:
- API - Add SDK-only workflow metadata api#336
- Go - Support workflow metadata query sdk-go#601
- Java - Support workflow metadata query sdk-java#335
- TypeScript - feat(worker): Add a workflow metadata query sdk-typescript#1319
- Python - [Feature Request] Support workflow metadata query sdk-python#467
- .NET - [Feature Request] Support workflow metadata query sdk-dotnet#185
