Example 1 with ZstdCompressor

use of io.airlift.compress.zstd.ZstdCompressor in project presto by prestodb.

the class TestParquetCompressionUtils method performTest.

private void performTest(CompressionCodecName codec, int inputLength) throws IOException {
    Compressor compressor = null;
    if (codec.equals(ZSTD)) {
        compressor = new ZstdCompressor();
    } else if (codec.equals(LZ4)) {
        compressor = new Lz4Compressor();
    }
    byte[] input = createArray(inputLength);
    byte[] output = new byte[inputLength + 512];
    int retLength = compress(compressor, input, inputLength, output, 0);
    Slice decompressedSlice = ParquetCompressionUtils.decompress(codec, wrappedBuffer(output, 0, retLength), inputLength);
    assertEquals(decompressedSlice, wrappedBuffer(input));
}
