[jira] [Updated] (ZOOKEEPER-3163) Use session map to improve the
performance when closing session in Netty
[ https://issues.apache.org/jira/browse/ZOOKEEPER-3163?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Fangmin Lv updated ZOOKEEPER-3163:
----------------------------------
Description:
Previously, it needs to go through all the cnxns to find out the session to close, which is O(N), N is the total connections we have.
This will affect the performance of close session or renew session if there are lots of connections on this server, this JIRA is going to reuse the session map code in NIO implementation to improve the performance.
