Struct FiltersFeature 

pub struct FiltersFeature {
    pub enable: bool,
    pub meta: MetaFilters,
    pub indicators: IndicatorFilters,
    pub sql: SqlFilters,
}

过滤器配置 (重构后)

Fields

enable: bool

是否启用过滤器

meta: MetaFilters

元数据过滤器 (记录级: 只要命中其中一个就保留该记录 - OR 逻辑)

indicators: IndicatorFilters

指标过滤器 (事务级: 命中即保留整笔事务 - 需要预扫描)

sql: SqlFilters

SQL 内容过滤器 (事务级: 未来扩展)

Implementations

impl FiltersFeature

pub fn validate()

pub fn has_filters(&self) -> bool

检查是否配置了任何过滤器

pub fn has_transaction_filters(&self) -> bool

检查是否提供了需要预扫描的过滤器 (Transaction-level)

pub fn should_keep( &self, ts: &str, trxid: &str, ip: &str, sess: &str, thrd: &str, user: &str, stmt: &str, app: &str, tag: Option<&str>, ) -> bool

检查记录是否应该被保留 逻辑：(满足时间过滤) AND ( (没有任何其他过滤) OR (满足任一元数据过滤) OR (属于被选中的事务) )

pub fn merge_found_trxids(&mut self, trxids: Vec<String>)

合并预扫描发现的事务 ID 到 MetaFilters 中，以便在正式扫描时直接通过 trxid 匹配保留整笔事务
