Hi, the registry SPI will provide the implementation of etcd3. Therefore, we need to introduce a new jar (jetcd-core, jetcd-launcher (test)), which complies with the Apache-2.0 License. I checked his related dependencies to make sure it complies with the license of the Apache project.
Mainly dependent jar: grpc-core grpc-netty grpc-protobuf grpc-stub grpc-grpclb netty-all failsafe github address:https://github.com/etcd-io/jetcd license:https://github.com/etcd-io/jetcd/blob/master/LICENSE notice:https://github.com/etcd-io/jetcd/blob/master/NOTICE Maven repository: https://mvnrepository.com/artifact/io.etcd/jetcd-core https://mvnrepository.com/artifact/io.etcd/jetcd-launcher Best wishes！ CalvinKirs
