What rpc frameworks are there?

rpc frameworks include: 1. gRPC, a high-performance, open source RPC framework developed by Google; 2. Apache Thrift, a cross-language RPC framework developed and open source by Facebook; 3. Apache Dubbo, a high-performance Performance, lightweight RPC framework, suitable for large-scale distributed systems; 4. Apache Axis2, an RPC framework based on Web service standards; 5. Spring Cloud, an open source framework for building distributed systems.

RPC (Remote Procedure Call) is a communication mode in a distributed system. It is used to implement communication and calls between different processes or different machines, so that the caller can call a local function just like calling a local function. Call a remote function or method. The RPC framework is a software library or tool used to implement RPC functions. It provides a complete set of communication protocols and programming interfaces, simplifying the development of distributed systems.

The following are several common RPC frameworks:

1. gRPC: gRPC is a high-performance, open source RPC framework developed by Google. It uses Protocol Buffers (protobuf) as the interface definition language (IDL) and supports multiple programming languages, such as Java, C, Python, etc. gRPC is based on the HTTP/2 protocol and supports bidirectional stream communication, multiple serialization formats (such as protobuf and JSON, etc.), and load balancing.

2. Apache Thrift: Apache Thrift is a cross-language RPC framework developed and open sourced by Facebook. It uses its own IDL language and supports multiple programming languages ​​such as Java, C, Python, Ruby, etc. Thrift provides richer functions than gRPC, including asynchronous IO, connection pooling, composite types, etc., and is suitable for a variety of scenarios.

3. Apache Dubbo: Apache Dubbo (formerly Alibaba Dubbo) is a high-performance, lightweight RPC framework suitable for large-scale distributed systems. Dubbo uses Java annotations for service declaration, supports multiple load balancing strategies and cluster fault tolerance mechanisms, and provides rich monitoring and management functions.

4. Apache Axis2: Apache Axis2 is an RPC framework based on Web service standards. It supports the SOAP protocol, describes the service interface through WSDL, and supports multiple programming languages, such as Java, C, Python, etc. Axis2 provides a highly scalable architecture, security and reliability, and supports publishing and discovery services.

5. Spring Cloud: Spring Cloud is an open source framework for building distributed systems. It provides multiple modules, including service discovery and registration, load balancing, circuit breaker, intelligent routing and other functions, and realizes communication and invocation between services based on HTTP or RPC. Spring Cloud integrates a variety of RPC frameworks, such as RestTemplate, Feign, Ribbon, etc., allowing developers to easily build distributed systems.

It should be noted that the selection of RPC framework should be based on actual needs and project conditions, including performance, language support, functional features, ease of use and other factors that need to be considered. In addition, the appropriate RPC framework can be selected based on the development team's experience and technology stack.
