+## Caching
+
+To reduce database load and improve performance, integration configurations are cached in-memory as a Dictionary
+with a periodic load of all configurations. Without caching, each incoming `EventMessage` would trigger a database
+query to retrieve the relevant `OrganizationIntegrationConfigurationDetails`.
+
+By loading all configurations into memory on a fixed interval, we ensure:
+
+- Consistent performance for reads.
+- Reduced database pressure.
+- Predictable refresh timing, independent of event activity.
+
+### Architecture / Design
+
+- The cache is read-only for consumers. It is only updated in bulk by a background refresh process.
+- The cache is fully replaced on each refresh to avoid locking or partial state.
+- Reads return a `List<OrganizationIntegrationConfigurationDetails>` for a given key or an empty list if no
+  match exists.
+- Failures or delays in the loading process do not affect the existing cache state. The cache will continue serving
+  the last known good state until the update replaces the whole cache.
+
+### Background Refresh
+
+A hosted service (`IntegrationConfigurationDetailsCacheService`) runs in the background and:
+
+- Loads all configuration records at application startup.
+- Refreshes the cache on a configurable interval.
+- Logs timing and entry count on success.
+- Logs exceptions on failure without disrupting application flow.
