Work on TRAFODION-3220 started by Hans Zeller. ---------------------------------------------- > Extend the existing compiler GUI to display query execution as well > ------------------------------------------------------------------- > > Key: TRAFODION-3220 > URL: https://issues.apache.org/jira/browse/TRAFODION-3220 > Project: Apache Trafodion > Issue Type: New Feature > Components: sql-exe > Affects Versions: 2.3 > Reporter: Hans Zeller > Assignee: Hans Zeller > Priority: Minor > Fix For: 2.4 > > > There have been several occasions where I wished we had a GUI debugging tool > for the executor that allows to single-step through work method calls and > that allows us to control multiple ESPs, so we can reproduce distributed > situations like "late cancel". It turns out this is relatively easy to do, so > I'm planning to submit a PR for this feature soon. > > The GUI will have one window for every fragment instance (the master fragment > instance and then one for each ESP fragment instance). This window will allow > to step one subtask (work method invocation, see class ExSubtask) at a time, > or it will allow to set breakpoints at specific subtasks, or one can resume > the instance without the GUI. I'm also adding a very primitive queue display, > but that will need more work, in the first version it won't be possible to > look at the data in the executor queues. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
