Updating Proto Definitions Without Updating Code, later in Protocol buffers allow for the seamless support ofĬhanges, including the addition of new fields and the deletion of existingįields, to any protocol buffer without breaking existing services. Google and data within them may persist for some time, maintaining backwardsĬompatibility is crucial. writeTo ( output ) īecause protocol buffers are used extensively across all manner of services at build () output = new FileOutputStream ( args ) john. Protocol buffer messages and services are described byĮngineer-authored. They are usedĮxtensively in inter-server communications as well as for archival storage ofĭata on disk. Protocol buffers are the most commonly-used data format at Google. Protocol buffers can beĮxtended with new information without invalidating existing data or requiring The format is suitable for bothĮphemeral network traffic and long-term data storage. Protocol buffers provide a serialization format for packets of typed, structuredĭata that are up to a few megabytes in size. That is written to a file (or sent across a network connection). proto files), the code that the proto compiler generates to interface withĭata, language-specific runtime libraries, and the serialization format for data

Protocol buffers are a combination of the definition language (created in

Of data streams and using a variety of languages. Source code to easily write and read your structured data to and from a variety You want your data to be structured once, then you can use special generated Smaller and faster, and it generates native language bindings. Protocol Buffers are a language-neutral, platform-neutral extensible mechanism for serializing structured data.
