[jira] [Commented] (CALCITE-4482) "ImmutableBeans.create" has performance issue

    [ https://issues.apache.org/jira/browse/CALCITE-4482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17276111#comment-17276111 ] 

Jiatao Tao commented on CALCITE-4482:
-------------------------------------

We are doing the stressing test, and we found SqlNode#toString' time is unusually high, seem we can reduce the useless call of ImmutableBeans.create to reduce the time:
