    @arshadmohammad Audit logging, when enabled, will for sure degrade performance as it adds
additional IO cost. Have you done any sort of performance evaluation so we can roughly get
an idea of what kind of performance expectation we should have when audit logging is enabled?

    
    Depends on how the performance degraded on different use cases, you might want to consider
adding an async version of audit logging otherwise this feature might not be usable (note
I am just guessing on the perf numbers here). Similar case happened on HDFS where an async
audit logging was added to avoid degrading performance on hotspots.
