Apache ShardingSphere Add ShardingSphere Kafka source connector
Apache ShardingSphere
Apache ShardingSphere is positioned as a Database Plus, and aims at building a standard layer and ecosystem above heterogeneous databases. It focuses on how to reuse existing databases and their respective upper layer, rather than creating a new database. The goal is to minimize or eliminate the challenges caused by underlying databases fragmentation.

Background
The community just added CDC (change data capture) feature recently. Change feed will be published in created network connection after logging in, then it could be consumed.
Since Kafka is popular distributed event streaming platform, it's useful to import change feed into Kafka for later processing.
Task
- Familiar with ShardingSphere CDC client usage, create publication and subscribe change feed.
- Familiar with Kafka connector development, develop source connector, integrate with ShardingSphere CDC. Persist change feed to Kafka topics properly.
Relevant Skills
1. Java language
2. Basic knowledge of CDC and Kafka
3. Maven

Dubbo GSoC 2023 - Refactor the http layer
Background
Dubbo currently supports the rest protocol based on http1, and the triple protocol based on http2, but currently the two protocols based on the http protocol are implemented independently, and at the same time, they cannot replace the underlying implementation, and their respective implementation costs are relatively high.
Target
In order to reduce maintenance costs, we hope to be able to abstract http. The underlying implementation of the target implementation of http has nothing to do with the protocol, and we hope that different protocols can reuse related implementations.

Dubbo GSoC 2023 - Refactor Connection
Background
At present, the abstraction of connection by client in different protocols in Dubbo is not perfect. For example, there is a big discrepancy between the client abstraction of connection in dubbo and triple protocols. As a result, the enhancement of connection-related functions in the client is more complicated, and the implementation cannot be reused. At the same time, the client also needs to implement a lot of repetitive code when extending the protocol.
Target
Reduce the complexity of the client part when extending the protocol, and increase the reuse of connection-related modules.

Dubbo GSoC 2023 - IDL management
Background
Dubbo currently supports protobuf as a serialization method. Protobuf relies on proto (Idl) for code generation, but currently lacks tools for managing Idl files. For example, for java users, proto files are used for each compilation. It is more troublesome, and everyone is used to using jar packages for dependencies.
Target
Implement an Idl management and control platform, support idl files to automatically generate dependency packages in various languages, and push them to relevant dependency warehouses
