In accordance with embodiments, there are provided mechanisms and methods for facilitating early detection and warning for system bottlenecks in an on-demand services environment according to one embodiment. In one embodiment and by way of example, a method includes detecting waits during processing of a query within a processing pipeline, wherein the waits include one or more of application-specific waits and database-specific waits; diagnosing the waits to identify a wait that has turned into a bottleneck; classifying one or more types of issues causing the wait to turn into the bottleneck; generating an alert having associated information detailing the issues based on the one or more types and a location of the wait within the processing pipeline; and transmitting the alert to facilitate correction activities.
