["Igor Seliverstov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-10755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16758287#comment-16758287 ] 

Igor Seliverstov commented on IGNITE-10755:
-------------------------------------------

[~rkondakov] The thing I not sure about is the CQ handler. Is it really necessary to keep pending events during the handler registration? I think it can be easily omitted by increasing registration write lock scope.
