Description: Event rate limiting in data processing systems is a crucial mechanism that allows controlling the number of events processed within a specified time frame. This process is essential to prevent system overload and ensure that resources are used efficiently. By setting limits on event rates, systems can better manage data flow, ensuring that important events are not lost due to excessive processing or network saturation. Rate limiting can be applied at different levels, either at the input level, where incoming events are controlled, or at the output level, where the amount of data sent to destinations is regulated. This functionality is particularly relevant in environments where large volumes of data are generated, such as in monitoring applications, log analysis, and event management systems. Additionally, it allows system administrators to adjust configurations according to the specific needs of their infrastructure, thus optimizing overall system performance and stability.
