Moving beyond basic LLMs, agent systems will reason, coordinate, and execute complex real-world transactions. Building on legacy data architectures will inherit the ills of the last 20 years.
Not sure i would say Spanner is the only database that can do this... first of all, this new thing from AWS can't do what spanner can do and second, there are few that can deliver distributed transactions in addition to Spanner, such as CockroachDB (ex-emplyer), Yagbyte and TiDB.
