## Description ### Problem When user creates a timeseries with tag or attribute, the tag/attribute record will be persisted to TagLogFile. Currently, every TagLogFile writing operation will be force flushed to disk, and too many disk I/O will cause poor performance. A example case is that, one timeseries creation costs 48ms and around 8000 timeseries with tag creation costs 5-6min. ### Solution Set the force flush mode of FileChannel to false and execute force flush every N writing operations. N is an customized interval value that user can config. -- This is an automated message from the Apache Git Service.
