Hi tison,

>1. Will TypeInformation be deprecated and we use DataType as type system everywhere?

AFAIK, runtime will still supports TypeInformation, while table module supports DataType

> 2. Schema in Table API currently support only TypeInformation to register a field, shall we support

the DataType way as well?

Schema also supports DataType since FLINK-14645[1]

Best,

Hi,

I notice that our type system has two branches. One  is TypeInformation while the other is

DataType. It is said that Table API will use DataType but there are several questions about

this statement:

1. Will TypeInformation be deprecated and we use DataType as type system everywhere?

2. Schema in Table API currently support only TypeInformation to register a field, shall we support

the DataType way as well?

Best,

tison.
