类 StreamOutputFile

java.lang.Object

org.apache.paimon.format.parquet.writer.StreamOutputFile

所有已实现的接口:

org.apache.parquet.io.OutputFile

public class StreamOutputFile
extends Object
implements org.apache.parquet.io.OutputFile

An implementation of Parquet's OutputFile interface that goes against a Paimon PositionOutputStream.

Because the implementation goes against an open stream, rather than open its own streams against a file, instances can create one stream only.
