It's still lukewarm since the Python process is kept around between query runs. The tag should be kept as is. Am I missing something?

@rschu1ze thanks for handling the issue. Are you going to rerun the benchmarks as well? The results are likely to change after your modifications.

I triggered the automation but all jobs fell victim to GitHub's outage today :-( Trying again now.

Same as with polars, the lukewarm-cold-run tag should be kept. Worth checking other changed results too, e.g. it looks like duckdb-dataframe also keeps Python process around.

GH seems running normally now. Could you retry?

Sure (however this PR is currently low priority for me, I work on it on the side, probably tomorrow or on the weekend).

Sorry, I just wanted to check if this PR is still on your radar. No need to rush, I understand the circumstances.

Hey team, quick question. I thought that the tag was for the systems that do not clear OS cache and do not restart with every query. Am I wrong?

Forcing to all the systems restarting for every query is that in the roadmap yet?

Thank you
