AWS announced a batch of “AI Agent tools” — one name I didn’t recognize was Tacnode. How does it compare to Timescale, Citus, etc.?

Caught part of the AWS Summit keynote where they introduced a new “AI Agents & Tools” section in the Marketplace. A few names were familiar (like Stripe, Confluent), but one that stood out just because I hadn’t heard of it before was Tacnode.

It was listed under API-based agent tools, and from the Marketplace description it looks like it’s Postgres-compatible and aimed at real-time or agent-style workloads. Claims stuff like:

• Streaming ingestion and updates
• Incremental materialized views
• Some kind of hybrid row/column storage
• Vector support?

Anyone know what this is or how it compares to tools like:

• TimescaleDB for time series
• Citus for distributed scaling
• pgvector for similarity search
• or alternatives like ClickHouse / DuckDB?

Just curious whether it’s doing something fundamentally different or just packaging familiar patterns in a new way.
