[jira] [Commented] (ARROW-14000) [C++] Add profiling / tracing for exec plan

["David Li (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-14000?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17415146#comment-17415146 ] 

David Li commented on ARROW-14000:
----------------------------------

I mean to get back to ARROW-12671 when I can find time, I really need to carve out some time and figure out the last issue (why Jaeger and the other reporting tools just don't work) unless we're ok maintaining our own visualizations (which may not necessarily be a bad choice depending on what we need from them).

> At a minimum we should be able to see how much time is spent in each node.
> Other nice reports to see:
>  * Bandwidth vs. time for each operator
>  * Some visualization of threading / parallelism
> This should be done in tandem with / on top of ARROW-12671
