## What it is
sofa-pbrpc is a lightweight C++ RPC library implementing Google's protobuf RPC framework, with sync/async calls, timeouts, compression, load balancing, and a web monitor. It was developed by Baidu and also provides a Python client library.

## Use cases
- build high-performance protobuf RPC services in C++
- make sync and async RPC calls with per-request timeouts
- load balance requests across multiple backend servers
- monitor RPC services via a built-in web dashboard
- call protobuf RPC services from Python
- compress RPC payloads transparently over the network

## When to choose
- you need a lightweight, high-performance protobuf RPC stack in C++
- you want built-in load balancing, fault tolerance, and flow control without extra infrastructure
- you need service/method/request-level timeout control
- you want a web-based monitor and profiling statistics for RPC services

## When to avoid
- you need gRPC or modern protobuf versions (it depends on protobuf 2.4.1)
- you need cross-platform support beyond Linux
- you want an actively developed project with recent community activity
- you need features like bidirectional streaming or HTTP/2

## Facets
- artifact type: library
- maturity: maintenance
- function: rpc, http-server, middleware, monitoring
- domain: microservices, backend, developer-tools, networking
- platform: cpp, python
- tags: protobuf, load-balancing, async-rpc, high-performance, baidu, linux
