What changed and why

Thanks for opening the repo for PRs. This changes databases/singlestore.json only. I work at SingleStore, so the box below is ticked.

• tagline: "Distributed SQL running transactions, analytics, vector and full-text search in one engine on live data." It now covers the workloads the profile already lists (104 chars).
• workloads: added rag. Full-text and vector search run in one SQL query with reranking.
• strengths: added "MCP server and SQL AI functions let AI agents query and act on live data."
• weaknesses: "Rowstore tables require data to fit in memory" became "Optional in-memory rowstore tables must fit in RAM; the default columnstore lives on local disk and tiers to object storage." The trade-off stays. The new text says which table type it covers, because columnstore is the default.
• useCases: "Replacing a MySQL + Elasticsearch + warehouse combination" became "Apps and AI agents that read and write live business data".
• tags: added rag.
• lastVerified: 2026-11-10.

Nothing else changed. The weaknesses on licensing, missing triggers and materialized views, and shard keys are all still there.
