java.util.zip.CRC32
A class that can be used to compute the CRC-32 of a data stream. @see Checksum @version 1.32, 11/17/05 @author David Connelly
org.apache.kafka.common.utils.Crc32
This class was taken from Hadoop org.apache.hadoop.util.PureJavaCrc32 A pure-java implementation of the CRC32 checksum that uses the same polynomial as the built-in native CRC32. This is to avoid the JNI overhead for certain uses of Checksumming where many small pieces of data are checksummed in succession. The current version is ~10x to 1.8x as fast as Sun's native java.util.zip.CRC32 in Java 1.6 @see java.util.zip.CRC32

      break;
    default:
      checksum = XXHashFactory.fastestInstance().newStreamingHash32(randomInt()).asChecksum();
      break;
