> Regardless of what’s chosen it might be something to work on documentation
wise to either start or improve visibility on common performance
tradeoffs/tweaks/gotchas for folks. It took me quite awhile to bisect that
difference between two scenarios I had assumed to be ~identical. But I’ve
certainly learned my lesson on the importance of statistics collection so I at
least have the benefit of moving that way up my list of priorities.
I filed a PR to try and improve the docs here
- https://github.com/apache/datafusion/pull/16157
I personally think the default would be good to change too. I filed a ticket
to track:
