The CT-DCS console supports top key analysis, which can display big key and hot key information in an instance in real time, and supports viewing a month of history of big keys and hotkeys. This function helps you comprehensively understand vital information such as the access frequency and number of elements of a key, thereby providing strong data support for subsequent optimization operations.
