Avro; Protobuf; I am going to use simple project which wraps and abstracts different serialization formats through simple interface and we'll use Unit test project to check the speed of the process and size of serialized data. So, my assumption is that when using those converters the binary data first must be deserialized into an object represenation and afterwards that object must be passed to the protobuf/Parquet converter to store it in Parquet. The input is a directory tree (namespace-like) in which each file is either a domain_message s or a type. 2021-06-14T10:56:45.
