Hi,

first, I think this is very cool!
To avoid this kind of problems (and make further implementations more easy) 
could we use something like protobuf or Avro or so as Serialization layer for 
the metadata objects?
This would help us to keep all drivers in sync...

What do you think?

    Hi,
    
    After investigation, I found the tsfile format of go version is almost the 
same with the latest TsFile format of java version, but unfortunately there are 
some differences between them: They have almost the same meta objects 
structures, but there are several attributes are not exactly the same.
    
    Maybe we can eliminate these differences together if necessary.

    Hi,
    
    Glad to see that Lenovo makes this module open sourced.
    
    I want to confirm that Is this go version follow the latest TsFile format?
