Yuanjian Li commented on SPARK-26222: ------------------------------------- Hi Reynold, the first PR track all file listing time into a independent phase, which happened in analyze, optimize and DataFrameReader/Writer, is this match your thoughts? > Scan: track file listing time > ----------------------------- > > Key: SPARK-26222 > URL: https://issues.apache.org/jira/browse/SPARK-26222 > Project: Spark > Issue Type: Sub-task > Components: SQL > Affects Versions: 2.4.0 > Reporter: Reynold Xin > Priority: Major > > We should track file listing time and add it to the scan node's SQL metric, > so we have visibility how much is spent in file listing. It'd be useful to > track not just duration, but also start and end time so we can construct a > timeline. > This requires a little bit design to define what file listing time means, > when we are reading from cache, vs not cache. > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
