AWS helps you seamlessly migrate your file transfer workflows to AWS Transfer Family by integrating with existing authentication systems, and providing DNS routing with Amazon Route 53 so nothing changes for your customers and partners, or their applications. With your data in Amazon S3, you can use it with AWS services for processing, analytics, machine learning, and archiving.
In order to ensure that the Transfer object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:. Describes a file transfer protocol-enabled server that you specify by passing the ServerId parameter. Describes the user assigned to the specific file transfer protocol-enabled server, as identified by its ServerId property.
Adds a Secure Shell SSH public key to a user account identified by a UserName value assigned to the specific file transfer protocol-enabled server, identified by ServerId.
Lists the users for a file transfer protocol-enabled server that you specify by passing the ServerId parameter. Updates the file transfer protocol-enabled server's properties after that server has been created.
An optional map of parameters to bind to every request sent by this service object. The endpoint URI to send requests to. The default endpoint is built from the configured region. You can either specify this object, or specify the accessKeyId and secretAccessKey options directly.
See AWS. Defaults to true. Pass a map to enable any of the following specific validation features:. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads.
Defaults to false. Note that setting this configuration option requires an endpoint to be provided explicitly to the service constructor. Body signing can only be disabled when using https. This config is only applicable to S3 client. Defaults to legacy. Only available for S3 buckets Defaults to true.
A set of options to configure the retry delay on retryable errors. Currently supported options are:. Specify 'latest' to use the latest possible version. Specify 'latest' for each individual that can use the latest available version.
Use this to compensate for clock skew when your system may be out of sync with the service time. Note that this configuration option can only be applied to the global AWS. Defaults to 0 milliseconds.
Possible values are: 'v2', 'v3', 'v4'.For a list of changes and features in a particular version, view the change log. For more information see the AWS Blog. For guidance on migrating your application from 1. See the following Github issues for details about additional features not yet in 2.

What's Different between the SDK for Java 1.11.x and 2.x
Making the most of your one-on-one with your manager or other leadership. Podcast The story behind Stack Overflow in Russian. Featured on Meta.TransferManager provides a simple API for uploading content to Amazon S3, and makes extensive use of Amazon S3 multipart uploads to achieve enhanced throughput, performance and reliability. When possible, TransferManager attempts to use multiple threads to upload multiple parts of a single upload at once.
When dealing with large content sizes and high bandwidth, this can have a significant increase on throughput. TransferManager is responsible for managing resources such as connections and threads; share a single instance of TransferManager whenever possible. Call TransferManager. It can also survive JVM crash, provided the information that is required to resume the transfer is given as input to the resume operation.
For more information on pause and resume, See Also: Upload. ExecutorFactory and TransferManagerBuilder. TransferManagerConfiguration getConfiguration Returns the configuration which specifies how this TransferManager processes requests.
Reuse TransferManager and client objects and share them throughout applications.
TransferManager and all AWS client objects are thread safe. TransferManager and client objects may pool connections and threads. Parameters: credentialsProvider - The AWS security credentials provider to use when making authenticated requests. Parameters: credentials - The AWS security credentials to use when making authenticated requests.
By default, the thread pool will shutdown when the transfer manager instance is garbage collected. Parameters: s3 - The client to use when making requests to Amazon S3. It is not recommended to use a single threaded executor or a thread pool with a bounded work queue as control tasks may submit subtasks that can't complete until all sub tasks complete.
Using an incorrectly configured thread pool may cause a deadlock I. Parameters: configuration - The new configuration specifying how this TransferManager processes requests. Returns: The configuration settings for this TransferManager.
This method is non-blocking and returns immediately i. When uploading options from a stream, callers must supply the size of options in the stream through the content length field in the ObjectMetadata parameter. If no content length is specified for the input stream, then TransferManager will attempt to buffer all the stream contents in memory and upload the options as a traditional, single part upload.
Because the entire stream contents must be buffered in memory, this can be very expensive, and should be avoided whenever possible.
Use the returned Upload object to query the progress of the transfer, add listeners for progress events, and wait for the upload to complete. If resources are available, the upload will begin immediately. Otherwise, the upload is scheduled and started as soon as resources become available.
The returned Upload object allows you to query the progress of the transfer, add listeners for progress events, and wait for the upload to complete.
If resources are available, the upload will begin immediately, otherwise it will be scheduled and started as soon as resources become available.
Schedules a new transfer to upload data to Amazon S3. Use the returned Download object to query the progress of the transfer, add listeners for progress events, and wait for the download to complete. Use the returned PresignedUrlDownload object to query the progress of the transfer, add listeners for progress events, and wait for the download to complete. S3 will overwrite any existing objects that happen to have the same key, just as when uploading individual files, so use with caution.
This method is useful for cleaning up any interrupted multipart uploads. TransferManager attempts to abort any failed uploads, but in some cases this may not be possible, such as if network connectivity is completely lost. Callers should also remember that uploaded parts from an interrupted upload may not always be automatically cleaned up, but callers can use abortMultipartUploads String, Date to clean up any upload parts.
This method is non-blocking and returns immediately before the copy has finished. TransferManager doesn't support copying of encrypted objects whose encryption materials are stored in an instruction file.Since then, we have received helpful feedback from the community, and learned more about the needs of mobile developers like you.
The Transfer Utility is a new client, with many of the same features as the Transfer Manager, but designed to be simpler and more efficient to use. With these APIs, pausing and resuming was not possible. Additionally, you had to specify the content size ahead of time, further reducing the usefulness of streams.
With the Transfer Utility there is one file based API for uploading and downloading, which you can always pause or resume on top of the automatic pause and resume functionality described below. The Transfer Utility makes tracking transfers more mobile friendly. The primary way of tracking transfers is through instances of the TransferObserver class. TransferObserver instances are returned from the download and upload methods.
They are automatically saved to local storage and can be queried for based on id, type upload, download, or anyor state such as paused from anywhere within the app as shown below. TransferObservers gives access to the state, the total bytes transferred thus far, the total bytes to transfer for easily calculating progress barsand a unique ID you can use to keep track of distinct transfers. You can also specify a TransferListener, which will be updated on state or progress change, as well as if an error occurs.
With the Transfer Manager, there is no guarantee a transfer can be paused, and there are multiple ways to attempt to pause. Also, pauses require developers to serialize metadata about the transfer to persistent storage which they must manage. The Transfer Utility handles persisting of all transfer metadata for you. If an app is killed, crashes, or loses internet connectivity, transfers are automatically paused. You can manually pause a transfer by id with pause transferIdpause all downloads or uploads with pauseAllWithType TransferType.
The Transfer Utility automatically pauses transfers in many scenarios. In the case that your transfer was paused due to loss of network connectivity, it will automatically resume when the network is available again. In the case that the transfer is manually paused, or the app is killed, it can be resumed with the resume transferId method. Overall, we have built the Transfer Utility as an improvement and simplification over the Transfer Manager.
We believe it fits better with the needs of customers and helps accelerate high quality app development. To help customers migrate from the Transfer Manager to the new Transfer Utility, we have posted a migration guide.AWS S3 Tutorial for Beginners
The step by step Getting Started Guide. As always, we really appreciate community feedback: as a comment on this blog, a post on our forums, or as a GitHub issue.If your application depends on these libraries, see Side by Side to learn how to configure your pom.
Refer to the SDK for Java 2. To add version 2 components to your project, simply update your pom. You must create all clients using the client builder method.
Constructors are no longer available. In version 2. The separate configuration classes enable you to configure different HTTP clients for async versus synchronous clients but still use the same ClientOverrideConfiguration class.
For a complete mapping of client configuration methods between 1. In the SDK for Java 2. All client class names are now fully camel cased and no longer prefixed by "Amazon". The SDK for Java version 1. Region and Regions classes in version 2. For more details about changes related to using the Region class, see Region Changes.
Clients and operation request and response objects are now immutable and cannot be changed after creation. To reuse a request or response variable, you must build a new object to assign to it. Instead the request object accepts RequestBodywhich is a stream of bytes. The asynchronous client accepts AsyncRequestBody. In parallel, the response object accepts ResponseTransformer for synchronous clients and AsyncResponseTransformer for asynchronous clients.
Exception class names, and their structures and relationships, have also changed. SdkException is the new base Exception class that all the other exceptions extend.
For a full list of the 2. In version 1. For security best practices, cross-region access is no longer supported for single clients. This is no longer allowed in version 2.
