Client Module
The client module in light-4j is a very important component in light platform for interactions between client to service or service to service in synchronous request/response over HTTPS and HTTP2. Microservices are expected to have high throughput and low latency so that multiple services can be chained together to fulfill one external request. This is why the client module is designed for direct connection between consumer and provider with the HTTP 2.0 over TLS connection cached on the consumer side for most high throughput applications. For low throughput consumer, the connection can be closed after the request and reopen when the next request comes in.
There are a lot of features in the client module and these should be utilized in certain scenarios. The following section shows how to use the client module for common use cases and the detail usage is documented here as well.
