▲ 6 ▼ decode/encode thrift message without IDL

Why?

• because IDL generated model is ugly and inflexible, it is seldom used in application directly. instead we define another model, which leads to bad performance.
  • bytes need to be copied twice
  • more objects to gc
• thrift proxy can not know all possible IDL in advance, we need to decode/encode in a generic way to modify embedded header.
• official thrift library for go is slow, verified in several benchmarks. It is even slower than json-iterator
