Hi, My team and I try to measure total time spent on our flink job and found out that Flink takes 40ms ~ 100ms to proceed from one operator to another. I wonder how can we reduce this transition time.
Following DAG represents our job: and here is the screenshot of our log: at 19:37:04.564, the job is leaving "Source: Custom Source -> Flat Map" at 19:37:04.605, the job is entering "Co-Flat Map" at 19:37:04.605, the job is leaving "Co-Flat Map" at 19:37:04.705, the job is entering "Co-Flat Map -> ...." at 19:37:04.708, the job is leaving "Co-Flat Map -> ..." both "Co-Flat Map" finishes merely instantly, while most of the execution time is spent on the transition. Any idea? This is a UTF-8 formatted mail ----------------------------------------------- James C.-C.Yu +886988713275 +8615618429976
