Robert Schulze	fe8f84dccc	Exclude slow tests from fasttest profile ... 99% of all tests in the fasttest profile run in one sec or less. The excluded tests take 10 sec or more (the slowest being 02271_replace_partition_many_tables with 30 sec). Estimated savings: 7 min	2022-09-07 15:57:29 +00:00

Azat Khuzhin	61a2613127	Fix refcnt for unused MergeTree parts in SELECT queries ... Before this patch SELECT queries hold parts even if they were not required by select (had been eliminated by partition pruning). This defers removing parts if you have long running queries. This had been introduced in #23932, with introduction of StorageSnapshotPtr. Signed-off-by: Azat Khuzhin <a.khuzhin@semrush.com>	2022-06-08 07:04:53 +03:00
