pgbouncer mitigates connection

Source: Technology·Target: Failure Mode

Summary

PgBouncer multiplexes many client connections onto a small pool of PostgreSQL server connections, directly preventing connection exhaustion by bounding the number of server connections regardless of client count.

Evidence

·connection_exhaustion lists PgBouncer transaction-mode pooling as a prevents:true mitigation requiring pgbouncer (failure_modes/connection_exhaustion.yaml)
·pgbouncer advisor_rule: mandatory for serverless workloads that open a connection per invocation (technologies/pgbouncer.yaml)
