Cache water level control device and method, electronic equipment and storage medium

The embodiment of the invention provides a cache water level control device and method, electronic equipment and a storage medium, and relates to the technical field of data caching. The device comprises a water level adjusting module used for adjusting a cached current water level based on a currently executed frequency tracking mode; the water level detection module is used for detecting the cached current water level adjusted based on the currently executed frequency tracking mode in real time; the mode switching module is used for switching the currently executed frequency tracking mode into an active frequency tracking mode until the current water level is determined to be a balanced water level if the currently executed frequency tracking mode is determined to be a passive frequency tracking mode and the current water level does not meet a first preset condition; according to the embodiment of the invention, the dynamic balance of the water level of the cache can be always kept, and even if the write cl
