             Summary: Copying Stat in ZooCache is slow
                 Key: ACCUMULO-4798
             Project: Accumulo
          Issue Type: Improvement
    Affects Versions: 1.8.1, 1.7.3
            Reporter: Keith Turner
             Fix For: 1.9.0, 2.0.0

The ZooKeeper cache code caches Zookeeper stats.  When a stat is requested from 
the cache it copies it.  The ZK stat class offers no good way to copy other 
than serialize and deserialize.  The code currently does this and its slow.  
All code in Accumulo only uses one field from stat, so it would be much better 
to create a simple class that has this one field and can quickly copy.
