JSONEachRowWithProgress Format Enhancements in ClickHouse
TheJSONEachRowWithProgressformat will include events with metadata, as well as totals and extremes. It also includesrows_before_limit_at_leastandrows_before_aggregation. The format prints the exception properly if it arrives after partial results. The progress now includes elapsed nanoseconds. One final progress event is emitted at the end. The progress during query runtime will be printed no more frequently than the value of theinteractive_delaysetting. #74181 (Alexey Milovidov).
