Avro RPC

Avro RPC (Remote Procedure Call) is a method that allows different computer programs to communicate and exchange information over a network. It uses a compact data format and schema to ensure that both sender and receiver understand the data being shared. Avro RPC enables programs written in different programming languages to work together seamlessly by defining how data should be structured. This makes it easier to build distributed systems, where multiple programs run on different machines but need to interact with each other efficiently. Overall, it's a key tool for modern software development and data exchange.
