类 PartitionLoader

java.lang.Object

org.apache.flink.connector.file.table.PartitionLoader

所有已实现的接口:

Closeable, AutoCloseable

@Internal
public class PartitionLoader
extends Object
implements Closeable

Loader to temporary files to final output path and meta store. According to overwrite, the loader will delete the previous data.

This provide two interface to load: 1.loadPartition(java.util.LinkedHashMap<java.lang.String, java.lang.String>, java.util.List<org.apache.flink.core.fs.Path>): load temporary partitioned files, if it is new partition, will create partition to meta store. 2.loadNonPartition(java.util.List<org.apache.flink.core.fs.Path>): just rename all files to final output path.

TODO: src and dest may be on different FS.
