across distributed systems. High-performance querying for analytics, search, and AI workloads at scale. SQL simplicity to unify access across divers data types, reducing complexity in querying distributed datasets execute complex queries on very large data sets in the sub-second range. All with the simplicity of SQL. Optimizing for AI & Search is Difficult Optimizing for both structured analytics, full-text search complexity, storage costs, and maintenance overhead by consolidating disparate systems. The native SQL support also makes it simple to use as it provides a single and easy way to query the data. 4. Why

一个类 函数宏例子是可以像这样被调用的 sql! 宏： let sql = sql!(SELECT * FROM posts WHERE id=1); 这个宏会解析其中的 SQL 语句并检查其是否是句法正确的，这是比 macro_rules! 可以做到的 更为复杂的处理。sql! 宏会被定义为类似如此： #[proc_macro] pub fn sql(input: TokenStream)
