Example 1 with ZstdCompressorOutputStream

use of org.apache.commons.compress.compressors.zstandard.ZstdCompressorOutputStream in project flink by apache.

the class GenericCsvInputFormatTest method createTempZStandardFile.

private FileInputSplit createTempZStandardFile(String content) throws IOException {
    File tempFile = File.createTempFile("test_contents", "tmp.zst");
    tempFile.deleteOnExit();
    DataOutputStream dos = new DataOutputStream(new ZstdCompressorOutputStream(new FileOutputStream(tempFile)));
    dos.writeBytes(content);
    dos.close();
    return new FileInputSplit(0, new Path(tempFile.toURI().toString()), 0, tempFile.length(), new String[] { "localhost" });
}

Example 2 with ZstdCompressorOutputStream

use of org.apache.commons.compress.compressors.zstandard.ZstdCompressorOutputStream in project druid by druid-io.

the class CompressionUtilsTest method testDecompressZstd.

@Test
public void testDecompressZstd() throws IOException {
    final File tmpDir = temporaryFolder.newFolder("testDecompressZstd");
    final File zstdFile = new File(tmpDir, testFile.getName() + ".zst");
    Assert.assertFalse(zstdFile.exists());
    try (final OutputStream out = new ZstdCompressorOutputStream(new FileOutputStream(zstdFile))) {
        ByteStreams.copy(new FileInputStream(testFile), out);
    }
    try (final InputStream inputStream = CompressionUtils.decompress(new FileInputStream(zstdFile), zstdFile.getName())) {
        assertGoodDataStream(inputStream);
    }
