Jungtaek Lim commented on SPARK-25380:
--
IMHO it depends on how we see the issue and how we would like to tackle this.
If we think 200M of plan string is normal and usual, you're right the issue
lays in UI and UI should deal with it well.
(Even 200M of single plan would be out of expectation on end users and they
might miss to consider allocating enough space on driver side for UI, so
purging old plan would work for some cases but not for some other cases.)
If we don't think 200M of plan string is normal, we need to see actual case and
investigate which physical node occupies much space on representing, and
whether they're really needed or too verbose. If the huge string came from
representing physical node itself which doesn't change among batches, we may be
able to try storing template format of message for physical node and variables
separately and apply just when page is requested.
If we know more, we could have better solution: according to your previous
comment, I guess we're on the same page:
{quote}They seem to hold a lot more memory than just the plan graph structures
do, it would be nice to know what exactly is holding on to that memory.
{quote}
Since we are unlikely to get reproducer, I wouldn't want to block anyone to
work on this. Anyone could tackle on UI issue.

Another bit of information that would be useful is the breakdown of memory
usage of the {{SQLExecutionUIData}} instances. They seem to hold a lot more
memory than just the plan graph structures do, it would be nice to know what
