Redis cache refresh configuration

Foreword: Whether it is development or production, there is an operation to refresh redis_key, but there is no unified place to manage the redis_key used by some businesses (sometimes even need to find code location), based on this thinking, a configurable refresh cache architecture is made

Core idea: based on operations and KV loading to achieve refresh in different strategies (the idea is simple but the implementation is relatively complicated, see the table creation statement for details)

Currently, dimensions are implemented based on string and hash common operations

Select a specific strategy update class according to four dimensions
 handle_type: operation type update/delete
 key_kind: string hash
 key_type: do not load through sql, 1 load value_type through sql
 : configuration value, sql query string data, sql query object saves object value, sql query saves list data

The following is the corresponding figure

 

Create table statement
