<a name="best-practices-discovering-metadata"></a>

Amazon Redshift provides multiple ways to discover metadata. For applications and tools, including those built with AI agents, we recommend that you use the driver metadata API or `SHOW` commands for consistent, reliable, and performant metadata discovery.
