- `shadowAlgorithm` can act on multiple `shadowTableRule` at the same time
- `shadowAlgorithmType` currently supports `VALUE_MATCH`, `REGEX_MATCH` and `SIMPLE_HINT`
- `shadowTableRule` can be reused by different `shadowRuleDefinition`, so when executing `DROP SHADOW RULE`, the corresponding `shadowTableRule` will not be removed
