Alexander Kuzmenkov	087d8ab020	A follow-up for trace log overflow in perftests ... The start was in https://github.com/ClickHouse/ClickHouse/pull/11026 It turned out that the problem was due to the incorrect mutate() implementation that lead to quadratic amount of column copying. This problem has since been fixed. Remove the excessively verbose logging, and also change appendToBlock of LogElement's to accept mutable columns instead of accepting a block and mutating it on each call. It looks wasteful, even though it is almost a noop.	2020-05-21 23:40:23 +03:00
