方法详细资料

convertToSchema

public static org.apache.avro.Schema convertToSchema(org.apache.paimon.types.DataType schema,
                                                     Map<String,String> rowNameMapping)

Converts Paimon DataType (can be nested) into an Avro schema.

Use "org.apache.paimon.avro.generated.record" as the type name.

参数:

schema - the schema type, usually it should be the top level record type, e.g. not a nested type

返回:

Avro's Schema matching this logical type.

convertToSchema

public static org.apache.avro.Schema convertToSchema(org.apache.paimon.types.DataType dataType,
                                                     String rowName,
                                                     Map<String,String> rowNameMapping)

Converts Paimon DataType (can be nested) into an Avro schema.

The "{rowName}_" is used as the nested row type name prefix in order to generate the right schema. Nested record type that only differs with type name is still compatible.

参数:

dataType - logical type

rowName - the record name

返回:

Avro's Schema matching this logical type.

isArrayMap

public static boolean isArrayMap(org.apache.paimon.types.DataType type)

extractKeyTypeToAvroMap

public static org.apache.paimon.types.DataType extractKeyTypeToAvroMap(org.apache.paimon.types.DataType type)

extractValueTypeToAvroMap

public static org.apache.paimon.types.DataType extractValueTypeToAvroMap(org.apache.paimon.types.DataType type)
