Nikolai Kochetov	e57ad9cb7e	Update QueryPlan.cpp	2020-12-04 11:41:36 +03:00
Azat Khuzhin	ccd794a676	Add remerge_sort_lowered_memory_bytes_ratio setting ... Sometimes default ratio is not good enough (2), since it depends on lots of factors: - size of LIMIT - max_memory_usage - ... So add a separate setting for it. But note that it make sense to set remerge_sort_lowered_memory_bytes_ratio only in range (1, 2] Since <= 1 will just use more CPU, and > 2 will use more RAM and will unlikely be faster.	2020-11-29 21:16:42 +03:00
