Package org.apache.flink.formats.csv

Class CsvRowSchemaConverter

java.lang.Object
org.apache.flink.formats.csv.CsvRowSchemaConverter
public final class CsvRowSchemaConverter extends Object
Converter functions that covert Flink's type information to Jackson's CsvSchema.

In CsvSchema, there are four types (string, number, boolean, and array). In order to satisfy various Flink types, this class sorts out instances of TypeInformation and LogicalType that are not supported. It converts supported types to one of CsvSchema's types.

Note: Changes in this class need to be kept in sync with the corresponding runtime classes CsvRowDeserializationSchema and CsvRowSerializationSchema.
