Hi Tison, Migration from TypeInformation to DataType is a large work and will across many releases. As far as I can tell, we will finalize the work in 1.11. As godfrey said above, Flink SQL & Table API should always use DataType, DataStream uses TypeInformation.
Schema already supports DataType to register a field, and the the method using TypeInformation to register field is deprecated since 1.10.
