Add `LoadBalancer` for generalizing `EndpointSelector`

6

Motivation: A load-balancing strategy such as round robin can be used in `EndpointSelector` and elsewhere. For example, in the event loop scheduler, requests can be distributed using round robin to...

Add `StreamMessage.timeout()`

2

Currently, there is no timeout for `StreamMessage`'s `aggregate()` or `subscribe()`. If we want to give a timeout for `HttpRequest.aggregate()`, a separate scheduler needs to be run to abort the request...

Provide a way to detect unhealthy connections

Motivation: Currently, there is no extension point to detect errors for specific connections and terminate connections that are unhealthy. Related: #5717 #5751 API design: `OutlierDetector` is similar to `CircuitBreaker`, but...

Nested context paths

Currently, a context path is only supported at the root path. Nested context paths will help group and isolate each service. ```java sb.contextPath("/rest") .contextPath("/catalog") .service("/product", new GetProductService()) .service("/products", new ProductsHandler())...

`internal-service` provides `include` options to opt in services to serve only in the non-service port. But `exclude` isn't supported to opt out of `include`. `exclude` option will be useful for...

Currently, there is no way to actively detect errors for specific connections and terminate connections that are unhealthy. It would be useful when a server uses a load balancer as...

Add a graceful shutdown timeout before closing the default `ClientFactory`
