WebSocket makes it possible to open an interactive communication between a browser (front-end) and a server (back-end).. It’s a two-way communication protocol that allows not only communication from the front-end to the back-end, but also from the back-end to the front-end as well. 🚀Gev is a lightweight, fast non-blocking TCP network library based on Reactor mode. Support custom protocols to quickly and easily build high-performance servers. Jan 31, 2017 The WebSocket Server origin can use multiple threads to enable parallel processing of data from multiple WebSocket clients. The origin can also send responses back to the origin system when used in a microservice pipeline.. Before you configure the origin, perform additional steps to configure the WebSocket clients.

Google protobuf now also supports generating JS files. For ProtoBuf, row parsing is determined by information on the message's schema that you provide to s-Server (using options called SCHEMA_JAR and SCHEMA_CLASS). Using the ECD framework, you create a foreign stream and the ECD framework converts ProtoBuf messages into columns, which can be specified explicitly. Protobuf is a contract-first messaging format. An app's messages, including its fields and types, must be specified in.proto files when the app is built.
