   I'm also very disappointed in `upsert()` performance.. as it seems it 
doesn't use partition_filter at all! Am I missing something? 
   I have a large table (100m+ rows) partitioned by 
`company_id,day(created_at)` and each row then has a unique `id`.. 
   
   I would expect upserting with `join_cols=company_id,day(created_at),id` to 
actually use partition filtering so it doesn't scan all files, and then be 
super fast. 
   
   But it doesn't (am I missing something here?) and believe @EnyMan's #2943 
doesn't address that?
