I am calling AWS Storage Gateway refreshCache method quite too frequently I guess, (As the message suggests), but I am not sure how long do I need to wait till I hit it again, any help will be appreciated.

AWSStorageGateway gatewayClient = AWSStorageGatewayClientBuilder.standard().build();
 RefreshCacheRequest cacheRequest = new RefreshCacheRequest();
 cacheRequest.setFileShareARN(this.fileShareArn);
 gatewayClient.refreshCache(cacheRequest);

com.amazonaws.services.storagegateway.model.InvalidGatewayRequestException: Too many requests have been sent to server. (Service: AWSStorageGateway; Status Code: 400; Error Code: InvalidGatewayRequestException; Request ID: f1ffa249-6908-4ae1-9f71-93fe7f26b2af) at com.amazonaws.http.AmazonHttpClient$RequestExecutor.handleErrorResponse(AmazonHttpClient.java:1712) at com.amazonaws.http.AmazonHttpClient$RequestExecutor.executeOneRequest(AmazonHttpClient.java:1367) at com.amazonaws.http.AmazonHttpClient$RequestExecutor.executeHelper(AmazonHttpClient.java:1113) at com.amazonaws.http.AmazonHttpClient$RequestExecutor.doExecute(AmazonHttpClient.java:770)

I think you can refer to the official document. https://docs.aws.amazon.com/storagegateway/latest/APIReference/API_RefreshCache.html

As it said,

When this API is called, it only initiates the refresh operation. When the API call completes and returns a success code, it doesn't necessarily mean that the file refresh has completed. You should use the refresh-complete notification to determine that the operation has completed before you check for new files on the gateway file share.

So I guess after you called AWS Storage Gateway refreshCache method, you must wait until the refresh action completed. And if you call the method again during this period，some exceptions will be raised.

For the solution, you can refer to Monitoring Your File Share to set a notification.
