 ## Key Features
 
-- **Weather data import**: Excel batch import with async two-pass processing, progress tracking, multi-row INSERT optimization
-- **Statistical analysis**: Same-date-across-years summarization with Redis caching, multi-dimensional queries
-- **File monitoring**: Automatic directory watching (WatchService), MD5 deduplication, file lifecycle management (receive -> display -> archive)
-- **Real-time notifications**: SSE-based alert streaming, Spring event-driven broadcast
-- **Data scoping**: Dept-level row-level security via MyBatis-Plus interceptor with `@DataFilter` annotation
-- **Dynamic datasource**: Runtime datasource switching via `@DataSource` annotation with ThreadLocal context
-- **Job scheduling**: Quartz-based dynamic job management with online start/stop/configure
-- **Cloud storage**: Alibaba Cloud OSS, Qiniu, Tencent Cloud COS integration
