[jira] [Commented] (IOTDB-2125) Create a session,open 2 “pool-14-IoTDB-RPC-Client” threads

    [ https://issues.apache.org/jira/browse/IOTDB-2125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17455054#comment-17455054 ] 

刘珍 commented on IOTDB-2125:
---------------------------

看起来还是benchmark的问题，创建单个Session连接，对应创建1个“pool-14-IoTDB-RPC-Client”线程，没发现新建1个session打开2个client的现象。
