> Project: Spark
> Issue Type: Improvement

>
> This proposes to extend Spark instrumentation to add metrics aimed at
> understanding the performance of Python code called by Spark, via UDF, Pandas
> UDF or with MapPartittions. Relevant performance counters are exposed using
> the Spark Metrics System (based on the Dropwizard library). This allows to
> easily consume the metrics produced by executors, for example using a
> performance dashboard. See also the attached screenshot.
