             Summary: Reduce the frequency of RNG calls in SecureWALCellCodec#EncryptedKvEncoder
                 Key: HBASE-11446
                 URL: https://issues.apache.org/jira/browse/HBASE-11446
             Project: HBase
          Issue Type: Improvement
            Reporter: Andrew Purtell
            Assignee: Andrew Purtell
             Fix For: 0.99.0, 0.98.4


By reducing the frequency of RNG calls in SecureWALCellCodec#EncryptedKvEncoder we can save 37% of on CPU time in that method and 3% of total on CPU time during an ingest test. WAL processing is a critical latency sensitive area.
