Class AvroGenericRecordToRowDataMapper

java.lang.Object

org.apache.iceberg.flink.sink.AvroGenericRecordToRowDataMapper

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.MapFunction<org.apache.avro.generic.GenericRecord,org.apache.flink.table.data.RowData>

public class AvroGenericRecordToRowDataMapper
extends Object
implements org.apache.flink.api.common.functions.MapFunction<org.apache.avro.generic.GenericRecord,org.apache.flink.table.data.RowData>

This util class converts Avro GenericRecord to Flink RowData.

Internally it uses Flink AvroToRowDataConverters. Because of the precision difference between how Iceberg schema (micro) and Flink AvroToRowDataConverters (milli) deal with time type, we can't directly use the Avro Schema converted from Iceberg schema via AvroSchemaUtil.convert(org.apache.iceberg.Schema, String).
