# Connection Saturation

Scaling & Performance

The state where all available database connections are in use, causing new requests to queue or fail. A common bottleneck in high-concurrency environments, especially with agent workloads that open many parallel connections. Addressed by connection pooling, query optimization, and per-role connection limits.
