Hi all, I would like to start a discussion about possible server improvements in the next major version.
Biggest problems to solve: 1. no easy way to extend the server and add new endpoint. For example it would be nice to add a server status endpoint, but it's not that easy to do. 2. improve the possibility to extend server by providers. This includes the ability to add new endpoints, protocols and handlers, to expand monitoring and logging capabilities, import / export, etc. 3. get rid of the need to change the pipe for some requests. It makes the code redundant and difficult to understand, especially for new developers. 4. code duplication in channelizers and handlers. Now we have to support the same code in different places. 5. low code separation, no boundaries between different subsystems. I think this will improve the ability to test various components. Proposed solution: Use microkernel architecture Key requirements: 1. Same handlers can be used for both TP3 and TP4 2. All existing handlers may be reused with small/no changes Server should have: 1. only the necessary infrastructure for adding services 2. single channelizer 3. one custom handler, which will choose how to process the request and call appropriate service 4. infrastructure to allow communication between services 5. management for lifecycle of services (init/shutdown...) Each service: 1. can be added and configured by changing config file (yaml), similar to how we manage serializers now 2. can decide to handle any request by request type/routes/protocols 3. can be built as an existing handler wrapper 4. can share data or code with other services Each request: 1. can be handled by 1 or more service. Service can indicate if request processing is finished. 2. can be handled with a server fallback code (just 404) p.s. Auth is just one more service Regards, Valentyn
