Sep 18, 2018 · Avro versus Protobuf There is an interesting comparison in this post that compares Avro, Protobuf and Thrift of binary messages sizes and how well the protocol supports schema evolution. Another interesting data transfer protocol is Parquet , which is optimized for column- oriented data. Avro over Kafka can be problematic because of the direct dependency of Avro messages on an Avro schema. Avro messages are binary so are not human readable. To deserialize an Avro message, the receiver must first have the correct Avro schema. Since each table from the source database results in a separate Avro schema, this can be problematic.

3.5 Protocol Buffers. Protocol Buffers is a format for data serialization. Google developed Protocol Buffers to solve problems with the versioning of interfaces. Today Google uses Protocol Buffers to store and exchange data in a lot of Google internal applications.
Stomp python moduleAvro data is described by a schema, and one interesting feature is that the schema is stored in the same file as the data it describes, so files are self-describing. Avro does not require code generation. This framework can compete with other similar tools like: Apache Thrift, Google Protocol Buffers, ZeroC ICE, and so on. 1. Apache Avro Cross-cutting hierarchies and superposition structures rather than just sets or trees of key-value pairs (Protobuf, Avro, Json, XML, SQL); Networks implementing a multi-level construal rather than just class inheritance or "composition" in OOP; • Analysing perspectives which usually go under radar in the mainstream IT practice : Apr 02, 2017 · It seems that every day, some computer monkey comes up with a new and more groovy serialization protocol.

I tried protobuf editor which works great for protocol buffers and have some plugin for avro called avro editor. It works fine for simple avro schemas which doesn't contain unions. What is very limiting and for practical use cases not usable. Requirements: should support all Avro data types (primitive and complex) - serve as data file viewer Mips dynamic arrayJun 26, 2018 · For Microsoft Avro I did not find a fast serializable method but its serialized string size is good. It has some bug preventing it from passing serialized type to the class (see the comments in code). I am really frustrated by Avro, it cannot run fast in my extremely simple code. It cannot fit in my simple serializing interface. .
