Subject [jira] [Updated] (ZOOKEEPER-3180) Add response cache to improve the throughput of read heavy traffic
Date Fri, 19 Oct 2018 21:55:00 GMT

     [ https://issues.apache.org/jira/browse/ZOOKEEPER-3180?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Fangmin Lv updated ZOOKEEPER-3180:
----------------------------------
    Description: 
On read heavy use case with large response data size, the serialization of response takes
time and added overhead to the GC.

Add response cache helps improving the throughput we can support, which also reduces the
latency in general.

This Jira is going to implement a LRU cache for the response, which shows some performance
gain on some of our production ensembles.
