[jira] [Commented] (CALCITE-2301) JDBC adapter: use query timeout from the top-level statement

    [ https://issues.apache.org/jira/browse/CALCITE-2301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16737473#comment-16737473 ] 

Julian Hyde commented on CALCITE-2301:
--------------------------------------

[~vlsi] I see you added a PR. It looks very good. It still needs a test, and I think we need to set the deadline based on query execution start time, otherwise we may have a race condition.

> It's not a good idea to have the magic number here. Also, databases may not get back within 10 second for various reasons (e.g., in the case of JDBC schema).
