**suggestion:** Consider lowering the log level or throttling the "cache refresh disabled" message to avoid log noise.

Because `SyncData` may be called frequently, this `LogInfo` will be emitted on every call while advisory refresh is disabled, creating excessive log noise. Consider downgrading to debug level or logging this only once (e.g., on first evaluation of the flag) instead of on every invocation.

```suggestion
	// refresh caches
	if tasks.EnableAdvisoryCacheRefresh {
		caches.RefreshAdvisoryCaches()
	} else {
		utils.LogDebug("Advisory cache refresh is disabled")
	}

	utils.LogInfo("Data sync finished successfully")
```
</issue_to_address>
