Asynchronous client for accessing AmazonElasticFileSystem. All asynchronous calls made using this client are non-blocking. Callers could either process the result and handle the exceptions in the worker thread by providing a callback handler when making the call, or use the returned Future object to check the result of the call in the calling thread. Amazon Elastic File System
  
          implements AmazonElasticFileSystemAsync {

    
Executor service for executing asynchronous requests.
  
      private ExecutorService executorService;
  
      private static final int DEFAULT_THREAD_POOL_SIZE = 50;

    
Constructs a new asynchronous client to invoke service methods on AmazonElasticFileSystem. A credentials provider chain will be used that searches for credentials in this order:

Creates a new, empty file system. The operation requires a creation token in the request that Amazon EFS uses to ensure idempotent creation (calling the operation with same creation token has no effect). If a file system does not currently exist that is owned by the caller's AWS account with the specified creation token, this operation does the following:

  • Creates a new, empty file system. The file system will have an Amazon EFS assigned ID, and an initial lifecycle state "creating".
  • Returns with the description of the created file system.

Otherwise, this operation returns a FileSystemAlreadyExists error with the ID of the existing file system.

NOTE:For basic use cases, you can use a randomly generated UUID for the creation token.

The idempotent operation allows you to retry a CreateFileSystem call without risk of creating an extra file system. This can happen when an initial call fails in a way that leaves it uncertain whether or not a file system was actually created. An example might be that a transport level timeout occurred or your connection was reset. As long as you use the same creation token, if the initial call had succeeded in creating a file system, the client can learn of its existence from the FileSystemAlreadyExists error.

NOTE:The CreateFileSystem call returns while the file system's lifecycle state is still "creating". You can check the file system creation status by calling the DescribeFileSystems API, which among other things returns the file system state.

After the file system is fully created, Amazon EFS sets its lifecycle state to "available", at which point you can create one or more mount targets for the file system (CreateMountTarget) in your VPC. You mount your Amazon EFS file system on an EC2 instances in your VPC via the mount target. For more information, see Amazon EFS: How it Works

This operation requires permission for the elasticfilesystem:CreateFileSystem action.

Parameters:
createFileSystemRequest Container for the necessary parameters to execute the CreateFileSystem operation on AmazonElasticFileSystem.
Returns:
A Java Future object containing the response from the CreateFileSystem service method, as returned by AmazonElasticFileSystem.
Throws:
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonElasticFileSystem indicating either a problem with the data in the request, or a server side issue.

Deletes the specified mount target.

This operation forcibly breaks any mounts of the file system via the mount target being deleted, which might disrupt instances or applications using those mounts. To avoid applications getting cut off abruptly, you might consider unmounting any mounts of the mount target, if feasible. The operation also deletes the associated network interface. Uncommitted writes may be lost, but breaking a mount target using this operation does not corrupt the file system itself. The file system you created remains. You can mount an EC2 instance in your VPC using another mount target.

This operation requires permission for the following action on the file system:

  • elasticfilesystem:DeleteMountTarget

NOTE:The DeleteMountTarget call returns while the mount target state is still "deleting". You can check the mount target deletion by calling the DescribeMountTargets API, which returns a list of mount target descriptions for the given file system.

The operation also requires permission for the following Amazon EC2 action on the mount target's network interface:

  • ec2:DeleteNetworkInterface

Parameters:
deleteMountTargetRequest Container for the necessary parameters to execute the DeleteMountTarget operation on AmazonElasticFileSystem.
Returns:
A Java Future object containing the response from the DeleteMountTarget service method, as returned by AmazonElasticFileSystem.
Throws:
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonElasticFileSystem indicating either a problem with the data in the request, or a server side issue.

Returns the description of a specific Amazon EFS file system if either the file system CreationToken or the FileSystemId is provided; otherwise, returns descriptions of all file systems owned by the caller's AWS account in the AWS region of the endpoint that you're calling.

When retrieving all file system descriptions, you can optionally specify the MaxItems parameter to limit the number of descriptions in a response. If more file system descriptions remain, Amazon EFS returns a NextMarker , an opaque token, in the response. In this case, you should send a subsequent request with the Marker request parameter set to the value of NextMarker .

So to retrieve a list of your file system descriptions, the expected usage of this API is an iterative process of first calling DescribeFileSystems without the Marker and then continuing to call it with the Marker parameter set to the value of the NextMarker from the previous response until the response has no NextMarker .

Note that the implementation may return fewer than MaxItems file system descriptions while still including a NextMarker value.

The order of file systems returned in the response of one DescribeFileSystems call, and the order of file systems returned across the responses of a multi-call iteration, is unspecified.

This operation requires permission for the elasticfilesystem:DescribeFileSystems action.

Parameters:
describeFileSystemsRequest Container for the necessary parameters to execute the DescribeFileSystems operation on AmazonElasticFileSystem.
Returns:
A Java Future object containing the response from the DescribeFileSystems service method, as returned by AmazonElasticFileSystem.
Throws:
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonElasticFileSystem indicating either a problem with the data in the request, or a server side issue.

Creates a mount target for a file system. You can then mount the file system on EC2 instances via the mount target.

You can create one mount target in each Availability Zone in your VPC. All EC2 instances in a VPC within a given Availability Zone share a single mount target for a given file system. If you have multiple subnets in an Availability Zone, you create a mount target in one of the subnets. EC2 instances do not need to be in the same subnet as the mount target in order to access their file system. For more information, see Amazon EFS: How it Works .

In the request, you also specify a file system ID for which you are creating the mount target and the file system's lifecycle state must be "available" (see DescribeFileSystems).

In the request, you also provide a subnet ID, which serves several purposes:

  • It determines the VPC in which Amazon EFS creates the mount target.
  • It determines the Availability Zone in which Amazon EFS creates the mount target.
  • It determines the IP address range from which Amazon EFS selects the IP address of the mount target if you don't specify an IP address in the request.

After creating the mount target, Amazon EFS returns a response that includes, a MountTargetId and an IpAddress . You use this IP address when mounting the file system in an EC2 instance. You can also use the mount target's DNS name when mounting the file system. The EC2 instance on which you mount the file system via the mount target can resolve the mount target's DNS name to its IP address. For more information, see How it Works: Implementation Overview

Note that you can create mount targets for a file system in only one VPC, and there can be only one mount target per Availability Zone. That is, if the file system already has one or more mount targets created for it, the request to add another mount target must meet the following requirements:

  • The subnet specified in the request must belong to the same VPC as the subnets of the existing mount targets.

  • The subnet specified in the request must not be in the same Availability Zone as any of the subnets of the existing mount targets.

If the request satisfies the requirements, Amazon EFS does the following:

  • Creates a new mount target in the specified subnet.
  • Also creates a new network interface in the subnet as follows:
    • If the request provides an IpAddress , Amazon EFS assigns that IP address to the network interface. Otherwise, Amazon EFS assigns a free address in the subnet (in the same way that the Amazon EC2 CreateNetworkInterface call does when a request does not specify a primary private IP address).
    • If the request provides SecurityGroups , this network interface is associated with those security groups. Otherwise, it belongs to the default security group for the subnet's VPC.
    • Assigns the description "Mount target fsmt-id for file system fs-id" where fsmt-id is the mount target ID, and fs-id is the FileSystemId .
    • Sets the requesterManaged property of the network interface to "true", and the requesterId value to "EFS".

    Each Amazon EFS mount target has one corresponding requestor-managed EC2 network interface. After the network interface is created, Amazon EFS sets the NetworkInterfaceId field in the mount target's description to the network interface ID, and the IpAddress field to its address. If network interface creation fails, the entire CreateMountTarget operation fails.

NOTE:The CreateMountTarget call returns only after creating the network interface, but while the mount target state is still "creating". You can check the mount target creation status by calling the DescribeFileSystems API, which among other things returns the mount target state.

We recommend you create a mount target in each of the Availability Zones. There are cost considerations for using a file system in an Availability Zone through a mount target created in another Availability Zone. For more information, go to Amazon EFS product detail page. In addition, by always using a mount target local to the instance's Availability Zone, you eliminate a partial failure scenario; if the Availablity Zone in which your mount target is created goes down, then you won't be able to access your file system through that mount target.

This operation requires permission for the following action on the file system:

  • elasticfilesystem:CreateMountTarget

This operation also requires permission for the following Amazon EC2 actions:

  • ec2:DescribeSubnets
  • ec2:DescribeNetworkInterfaces
  • ec2:CreateNetworkInterface

Parameters:
createMountTargetRequest Container for the necessary parameters to execute the CreateMountTarget operation on AmazonElasticFileSystem.
Returns:
A Java Future object containing the response from the CreateMountTarget service method, as returned by AmazonElasticFileSystem.
Throws:
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonElasticFileSystem indicating either a problem with the data in the request, or a server side issue.
