> I have found that Char type data length is 100 instead of defined 50.
> we could help users to deal with the following data types in a proper way,
> thus allow the datagen connector to automatically generate data that conforms
> to the schema definition without additional manual configuration.
> # fixed-length data types (char, binary) , the length should be defined by
> schema definion, and could not be user-defined length.
> # variable-length data types (varchar, varbinary), the length should be
> defined by schema definition, and could be the user-defined length which less
> than schema definition.
