### AI overview

This guide explains how serverless databases provide managed, usage-based infrastructure that can scale to zero and support bursty AI application workloads. It examines persistence across agent memory, files, operational state, and retrieval data, and discusses evaluating connection behavior, cold starts, and system boundaries.

### Source excerpt

A serverless database is a fully-managed database that automatically scales compute and storage with demand, requires no server provisioning or capacity planning, and bills only for actual usage, including scaling to zero when idle. The provider handles infrastructure; you handle data. That definition covers the category. It doesn't cover the problem most teams actually face [...] The post The Complete Agent State Stack: Memory, Files, and Serverless Database Persistence for AI Apps appeared first on TiDB.
