public static String getTypeName(org.apache.flink.api.common.typeinfo.TypeInformation<?> type)

normalizeTableSchema

public static org.apache.flink.table.api.TableSchema normalizeTableSchema(org.apache.flink.table.api.TableSchema schema)

The original table schema may contain generated columns which shouldn't be produced/consumed by TableSource/TableSink. And the original TIMESTAMP/DATE/TIME types uses LocalDateTime/LocalDate/LocalTime as the conversion classes, however, JDBC connector uses Timestamp/Date/Time classes. So that we bridge them to the expected conversion classes.
