ProfaneDB
Protobuf defines your schema You alredy defined your models in Protobuf. Why should you to do it again to store them in your database? Based on RocksDB ProfaneDB doesn't want to reinvent the wheel. It uses RocksDB for great performance, the simplest way possible. gRPC interface ProfaneDB is written in C++, but can be used from any language that supports gRPC. It just needs your schema, and there i

Protocol Buffers 入門
This document discusses messaging queues and platforms. It begins with an introduction to messaging queues and their core components. It then provides a table comparing 8 popular open source messaging platforms: Apache Kafka, ActiveMQ, RabbitMQ, NATS, NSQ, Redis, ZeroMQ, and Nanomsg. The document discusses using Apache Kafka for streaming and integration with Google Pub/Sub, Dataflow, and BigQuery

Simple Binary Encoding
Financial systems communicate by sending and receiving vast numbers of messages in many different formats. When people use terms like "vast" I normally think, "really..how many?" So lets quantify "vast" for the finance industry. Market data feeds from financial exchanges typically can be emitting tens or hundreds of thousands of message per second, and aggregate feeds like OPRA can peak at over 10

Schema evolution in Avro, Protocol Buffers and Thrift — Martin Kleppmann’s blog
Schema evolution in Avro, Protocol Buffers and Thrift Published by Martin Kleppmann on 05 Dec 2012. So you have some data that you want to store in a file or send over the network. You may find yourself going through several phases of evolution: Using your programming language’s built-in serialization, such as Java serialization, Ruby’s marshal, or Python’s pickle. Or maybe you even invent your ow

Looking for more details about "Group varint encoding/decoding" presented in Jeff's slides
That's referring to "variable integer encoding", where the number of bits used to store an integer when serialized is not fixed at 4 bytes. There is a good description of varint in the protocol buffer documentation. It is used in encoding Google's protocol buffers, and you can browse the protocol buffer source code. The CodedOutputStream contains the exact encoding function WriteVarint32FallbackTo
