Cap’n Proto Data Serialization
Cap’n Proto is an insanely fast data interchange format and capability-based RPC system. Think JSON, except binary.
#What is Cap’n Proto?
Cap’n Proto is a high-performance data serialization and RPC (Remote Procedure Call) framework designed for efficient communication over networks. It was created by Kenton Varda at Cloudflare and was open-sourced in 2014. Cap’n Proto aims to be faster and more efficient than other serialization frameworks like Protocol Buffers and Thrift.
#Cap’n Proto Key Features
Here are some of the most recognizable features of Cap’n Proto:
- Low memory overhead: Cap’n Proto is designed to minimize the amount of memory required for serialization and deserialization.
- Zero-copy: Cap’n Proto supports zero-copy serialization and deserialization, which means that the serialized data can be sent directly over the network without copying it into a separate buffer.
- Dynamic schema evolution: Cap’n Proto supports dynamic schema evolution, which allows changes to the data structure without breaking backwards compatibility.
- RPC support: Cap’n Proto includes a built-in RPC system that allows for efficient communication between processes over a network.
- Language support: Cap’n Proto provides language bindings for a variety of programming languages, including C++, Python, Rust, and Go.
- Cross-platform support: Cap’n Proto is designed to work on a variety of platforms, including Linux, macOS, Windows, and various embedded systems.
#Cap’n Proto Use-Cases
Here are some use cases of Cap’n Proto:
- Network communication: Cap’n Proto is ideal for sending data over a network due to its low memory overhead, zero-copy support, and efficient serialization and deserialization.
- Distributed systems: Cap’n Proto’s RPC system makes it well-suited for building distributed systems where processes need to communicate efficiently.
- High-performance applications: Cap’n Proto’s focus on speed and efficiency makes it a good choice for applications that require high performance, such as real-time systems and game engines.
#Cap’n Proto Summary
Cap’n Proto is a high-performance data serialization and RPC framework designed for efficient communication over networks. It provides low memory overhead, zero-copy support, dynamic schema evolution, built-in RPC system, language bindings, and cross-platform support, making it well-suited for network communication, distributed systems, and high-performance applications.
