Jun Liu updated DUBBO-33:
-------------------------
Description:
* Programming language: Java
* Area: RPC Framework
* Keywords: RPC, HTTP2, LoadBalance, Circuit Breaker, Microservices, Cloud
Native, Reactive
Apache Dubbo (incubating) is a high-performance RPC framework that has already
been tested in widespread production in large scales. The Dubbo community has
grown a lot with high speed since joined ASF in 2018, with 100+ new
contributors and 20+ new committers joined.
This year with GSOC, we will focus on research of some core features Dubbo
needed to working as a core component in the modern distributed system, these
include development experience, stability, maintenance, performance and
integrating with new tech trends. In terms of technology topics, you will have
the practical opportunity to polish your skills in Microservice Architecture
Observability and Reliability, Cloud Native, Reactive and so on. Actually, some
of these topics are happening and discussing in the community and some
developers may have already started their work. But given the student's zero
backgrounds in Dubbo, in order to quick start, we will try to make these topics
into practical issues with detailed proposals and expectations.
We hope that the attendees can learn some of the key concepts of Microservice
and RPC and get the opportunity to build some of the core features of Dubbo.
And from the community's perspective, we cannot wait to see your intelligence
and bring the community some fresh ideas.
h2. Developement Experience
h2.
* Fluent -style Builder API build on ServiceConfig, ReferenceConfig, ...
* Easy-to-use Annotation
* <dubbo:service application="demo" registry="zookeeper" />
* Method-level annotation
* Annotation ans XML
* Put application-level configurations to a unified place, following the
path-based convention.

h2. Performance Tuning
* Service Discovery: avoid duplicate address computation, avoid recreate of URL.
* Share thread pool on the consumer side.
* Refine RPC protocol, avoid useless properties on the wire.
* ...
h2. Resilience and Stability
- Circuit Breaker: Instance and Cluster
- LoadBalance Policies: for example P2C, JWS
- Adaptive Concurrency Limit
- Heartbeat works as a mechanism of recognizing unhealthy connections
- Deadlines
- Fault Injection
- Thread Pool Isolation
h2. Observability
* Metrics counted and showed on Dubbo's own dashboard
* Being able to deliver metrics to open sourced projects like Prometheus.
h2. SPI Extension
* Service Directory: Consul, Etcd, ...
* Config Center: Consul, Etcd, ...
* Protocol: http2, ...
h2. Cloud Native and Reactive
* Built-in http2 support
* Interoperability with Microservice Architecture, for example, Spring Cloud.
* Adapt to K8S and ServiceMesh
* Fully async stack
* Reactive across processes.

And for the community's good, it would be better to have some fresh ideas.
