refresh-cache

Description

Refreshes the cache for the specified file share. This operation finds objects in the Amazon S3 bucket that were added, removed or replaced since the gateway last listed the bucket's contents and cached the results. This operation is only supported in the file gateway type. You can subscribe to be notified through an Amazon CloudWatch event when your RefreshCache operation completes. For more information, see Getting Notified About File Operations .

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. You can subscribe to be notified through an CloudWatch event when your RefreshCache operation completes.

Throttle limit: This API is asynchronous so the gateway will accept no more than two refreshes at any time. We recommend using the refresh-complete CloudWatch event notification before issuing additional requests. For more information, see Getting Notified About File Operations .

If you invoke the RefreshCache API when two requests are already being processed, any new request will cause an InvalidGatewayRequestException error because too many requests were sent to the server.

For more information, see "https://docs.aws.amazon.com/storagegateway/latest/userguide/monitoring-file-gateway.html#get-notification".

Synopsis

  refresh-cache
--file-share-arn <value>
[--folder-list <value>]
[--recursive | --no-recursive]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--file-share-arn (string)

The Amazon Resource Name (ARN) of the file share you want to refresh.

--folder-list (list)

A comma-separated list of the paths of folders to refresh in the cache. The default is ["/" ]. The default refreshes objects and folders at the root of the Amazon S3 bucket. If Recursive is set to "true", the entire S3 bucket that the file share has access to is refreshed.

Syntax:

"string" "string" ...

--recursive | --no-recursive (boolean)

A value that specifies whether to recursively refresh folders in the cache. The refresh includes folders that were in the cache the last time the gateway listed the folder's contents. If this value set to "true", each folder that is listed in FolderList is recursively updated. Otherwise, subfolders listed in FolderList are not refreshed. Only objects that are in folders listed directly under FolderList are found and used for the update. The default is "true".

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

FileShareARN -> (string)

The Amazon Resource Name (ARN) of the file share.

NotificationId -> (string)

The randomly generated ID of the notification that was sent. This ID is in UUID format.
