Protocol Buffer Basics: Python Protocol Buffers Google

6 days ago You can invent an ad-hoc way to encode the data items into a single string – such as encoding 4 ints as "12:3:-23:67". This is a simple and flexible approach, although it does require writing one-off encoding and parsing code, and the parsing imposes a small run-time cost. This works best for encoding very simple data. Serialize the data to XML.

I can write out a standard text file ( main.txt) which contains the data that I wish to marshal into a protobuf. 3 Extract. From here you are almost home. ... 4 Using “ decode” and “ encode”. ...

What is protoc and how do I use it?

A tool called protoc (standing for Protocol buffers compiler) is provided along with the libraries exactly for this purpose: given a.proto file in input, it can generate code for messages in several different languages. We only need the Python code, so after installing protoc we would execute the command: protoc --python_out=. metric.proto

Does Protobuf encode metric Type?

These are the results using Python 3.5.1 with protobuf 3.1.0 on a MacBook Pro (13-inch, Early 2015) to encode our Metric type, with and without Protobuf’ cpp extension, compared to the bogus text encoder from a few paragraphs ago. The encoding phase is where Protobuf spends more time.
