Creating an Offline Keys Analysis Task

Function

This API is used to create an offline key analysis task. The offline key analysis function analyzes the backup of a specific instance node. The analysis covers the top 100 big keys, top 50 keys with the most prefixes of each data type, and the memory usage and number of keys of each data type. Available only for DCS Redis 4.0, 5.0, 6.0, and enterprise edition instances.
