Alfred Davidson commented on SPARK-40281: ----------------------------------------- +1 in general this would be good regardless of access/usage pattern. Also having the option to have this exposed in the UI would be a bonus and will consolidate metrics (I can imagine many doing their own thing). I look forward to seeing what’s next > Memory Profiler on Executors > ---------------------------- > > Key: SPARK-40281 > URL: https://issues.apache.org/jira/browse/SPARK-40281 > Project: Spark > Issue Type: New Feature > Components: PySpark > Affects Versions: 3.4.0 > Reporter: Xinrong Meng > Priority: Major > > Profiling is critical to performance engineering. Memory consumption is a key > indicator of how efficient a PySpark program is. There is an existing effort > on memory profiling of Python programs, Memory Profiler > ([https://pypi.org/project/memory-profiler/).|https://pypi.org/project/memory-profiler/] > PySpark applications run as independent sets of processes on a cluster, > coordinated by the SparkContext object in the driver program. On the driver > side, PySpark is a regular Python process, thus, we can profile it as a > normal Python program using Memory Profiler. > However, on the executors side, we are missing such memory profiler. Since > executors are distributed on different nodes in the cluster, we need to > aggregate profiles. Furthermore, Python worker processes are spawned per > executor for the Python/Pandas UDF execution, which makes the memory > profiling more intricate. > The ticket proposes to implement a Memory Profiler on Executors. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
