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 500 big keys, top 500 keys with the most prefixes of each data type, and the memory usage and number of keys of each data type. Redis 3.0 instances do not support this API.

Calling Method

For details, see Calling APIs.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

  • If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
  • If you are using identity policy-based authorization, the following identity policy-based permissions are required.
