TsgcWSCircuitBreaker › Properties › PerEndpoint
Collection of pattern-based overrides that apply different Thresholds/Recovery per host.
property PerEndpoint: TsgcCircuitBreakerEndpointList read FPerEndpoint
write SetPerEndpoint;—
Each TsgcCircuitBreakerEndpointItem carries its own Pattern (wildcards * and ? supported), OverrideThresholds block and OverrideRecovery block. When the active key (usually the hostname derived from the outgoing URL) matches an enabled item, that item's settings replace the top-level Thresholds / Recovery for the duration of the call — the first enabled pattern match wins. Sub-properties: Enabled (False by default — when False no items are evaluated and only the top-level settings apply) and Items (a TCollection of endpoint overrides). Typical use: give api.openai.com lenient thresholds because it slows under load, while api.stripe.com opens fast because payment failures are critical.
