Very slow performance on query without index on simple documents

SQL++
9

Hi @geraldss

Thank you for your help, i really appreciate about it.
I have followed your instruction, but query still take nearly 6s.
It’s really too slow for get MAX timestamp.

SELECT MIN( -timestamp ) FROM gts WHERE accountid = ‘demo’ ;

I try to setting max_parallelism = 4 but it does not help either.
should i have to reference to any document optimization?

Best regards,
