📜 Description
DefaultCompositePerformanceCollector now stops the performance data collection for timeout on data collection rather than a scheduled background job
💡 Motivation and Context
Every time a transaction run, the SDK starts collecting performance data (cpu and ram usage) and schedules a timeout job after 30 seconds to stop this data collection.
Since v
8.19.0we have a limit on the queue of our background executor of 271 scheduled jobs. Any other scheduled job is ignored.This means that if a transaction runs forever and the background thread queue is full, its performance data will be collected forever, leading eventually to an OOM.
