Examples with RecordVectorizer org.apache.flink.orc.vector.RecordVectorizer used on opensource projects

Example 1 with RecordVectorizer

use of org.apache.flink.orc.vector.RecordVectorizer in project flink by apache.

the class OrcBulkWriterITCase method testOrcBulkWriter.

@Test
public void testOrcBulkWriter() throws Exception {
    final File outDir = TEMPORARY_FOLDER.newFolder();
    final StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
    final Properties writerProps = new Properties();
    writerProps.setProperty("orc.compress", "LZ4");
    final OrcBulkWriterFactory<Record> factory = new OrcBulkWriterFactory<>(new RecordVectorizer(schema), writerProps, new Configuration());
    env.setParallelism(1);
    env.enableCheckpointing(100);
    DataStream<Record> stream = env.addSource(new FiniteTestSource<>(testData), TypeInformation.of(Record.class));
    stream.map(str -> str).addSink(StreamingFileSink.forBulkFormat(new Path(outDir.toURI()), factory).withBucketAssigner(new UniqueBucketAssigner<>("test")).build());
    env.execute();
    OrcBulkWriterTestUtil.validate(outDir, testData);
}
