[GitHub] [incubator-doris] wutiangan opened a new issue #3969: explain verbose stmt to print detail explain infomartion about tupleDesc and slotDesc
wutiangan opened a new issue #3969:
URL: https://github.com/apache/incubator-doris/issues/3969
Now explain stmt only prints plannode and fragments.
Sometimes explain stmt needs to print upledesc and slotdesc to better trace problems and understand implementation details. Therefore, the syntax of explain verbose stmt is added on the basis of explain stmt.
If the user uses "explain verbose select stmt", the tupledesc and slotdesc information will be printed in addition to the normal fragment/plannode information.
If the user uses "explain select stmt", the execution plan is the same as before.
