Hi all. How much operation memory is expected QuestDB to consume if I have 5GB data on the disk.

Hi Sergey. It all depends on how complex queries you run. With sql it's possible to 'multiply 'dataset size and trigger materialization that'd end up using much more than 5GB of ram ( or disk).

Yes. My experience show the same. Is there a way to reduce memory consumed from sql query in exchange of its speed. Slow query is acceptable.

At the moment rewriting query and/or tweaking settings is the only way because qdb doesn't spill temporary data to disk. I could havea look if you share the schema and query .
