Sub-Second SQL Verification Algorithms for High-Concurrency BI
How multi-stage caching, cost estimation heuristics, and AST safety checks execute in under 30 milliseconds.

When hundreds of non-technical stakeholders are querying databases simultaneously, query generation and validation must not become a performance bottleneck.
ZeroQueries utilizes a multi-tiered compilation pipeline. First, intent is mapped against pre-compiled semantic graph fragments. Second, query cost is estimated against EXPLAIN plans to block runaway full-table scans.
Finally, the AST safety filter validates read-only constraints in under 30 milliseconds, allowing sub-second end-to-end turnaround even during peak business hours.
