Hi,
Starting a thread for adding Flink UDF metrics.
UDFs are widely used by Flink user, but they introduce significant challenges
when it comes to debugging and performance optimization. UDFs often act as
black boxes, making it difficult to trace issues or identify the root causes of
failures, especially when exceptions occur. The lack of dedicated metrics to
quantify critical aspects such as processing time and exception count
complicates debugging as well as performance tuning and resource allocation
These metrics will be disabled by default to prevent performance downgrade
and can be enabled through config.
