-------------------------------------------------------

             Summary: CRC32C for bookkeeper
                 Key: BOOKKEEPER-951
                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-951
             Project: Bookkeeper
          Issue Type: Improvement
          Components: bookkeeper-client
            Reporter: Venkateswararao Jujjuri (JV)


CRC32C is hardware based CRC32 and it substantially improves performance and practically offloads CPU. 

[~merlimat] at yahoo implemented this for Pulsar, opening this item to port that change.

Java 9 has CRC32C native support but we need this JNI patch to achieve it on Java 8.
