org.apache.flink.connectors.hive.read

Class HiveBulkFormatAdapter

java.lang.Object

org.apache.flink.connectors.hive.read.HiveBulkFormatAdapter

All Implemented Interfaces:

Serializable, org.apache.flink.api.java.typeutils.ResultTypeQueryable<org.apache.flink.table.data.RowData>, org.apache.flink.connector.file.src.reader.BulkFormat<org.apache.flink.table.data.RowData,HiveSourceSplit>

public class HiveBulkFormatAdapter
extends Object
implements org.apache.flink.connector.file.src.reader.BulkFormat<org.apache.flink.table.data.RowData,HiveSourceSplit>

A BulkFormat implementation for HiveSource. This implementation delegates reading to other BulkFormat instances, because different hive partitions may need different BulkFormat to do the reading.
