> Adding null-check before incrementing metrics for bytesSerialized
> Symptom: User serde-serialization logic can choose to serialize non-null objects to a null, which implies delete the value. In this case, current code tries to increment the metrics using the size of the null and fails with an NPE.
> Cause: Current code tries to increment the bytesSerialized metrics using the size of the null and fails with an NPE.
> Fix: Added logic to skip metric value update if serde returns null.
