-------------------------------------
Summary: Make the DataTree.approximateDataSize more efficient
Key: ZOOKEEPER-3116
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3116
Project: ZooKeeper
Issue Type: Improvement
Components: server
Reporter: Fangmin Lv
Assignee: Fangmin Lv
Fix For: 3.6.0
The approximateDataSize is a nice metric to show what's the total size stored
in ZooKeeper ensemble over time, but it's expensive to query too often, since
each query will go through all the nodes to calculate the total size.
It's better to use a counter to record the total data size when txns applied to
the DataTree, which is cheaper.
