[jira] [Commented] (GEARPUMP-288) It takes a long time to submit a big DAG on EmbeddedCluster

    [ https://issues.apache.org/jira/browse/GEARPUMP-288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15894264#comment-15894264 ] 

Manu Zhang commented on GEARPUMP-288:
-------------------------------------

We do {{getAcyclicCopy}} in case graph has cycles, which is slow. We can skip that if we there is no cycle.
