Persist job and task output to Azure Storage with the File Conventions library for . NET - Azure Batch. A task running in Azure Batch may produce output data when it runs. Task output data often needs to be stored for retrieval by other tasks in the job, the client application that executed the job, or both. Tasks write output data to the file system of a Batch compute node, but all data on the node is lost when it is reimaged or when the node leaves the pool.

6. You can create a bat file to run as administrator automatically itself. Here's a detailed guide on how to run batch programs as admin automatically.

Tasks may also have a file retention period, after which files created by the task are deleted. For these reasons, it's important to persist task output that you'll need later to a data store such as Azure Storage. One way to persist task data is to use the Azure Batch File Conventions library for . NET. The File Conventions library simplifies the process of storing task output data to Azure Storage and retrieving it. You can use the File Conventions library in both task and client code — in task code for persisting files, and in client code to list and retrieve them.

How to make a batch file in MS-DOS, Windows command line, and in Windows. With information on what to write in the batch file and how to run the batch file. Batch files help and information including a full list of questions and answers that help answer how to make, run, and edit batch files.

Your task code can also use the library to retrieve the output of upstream tasks, such as in a task dependencies scenario. To retrieve output files with the File Conventions library, you can locate the files for a given job or task by listing them by ID and purpose. You don't need to know the names or locations of the files. For example, you can use the File Conventions library to list all intermediate files for a given task, or get a preview file for a given job. Tip. Starting with version 2.

Batch service API supports persisting output data to Azure Storage for tasks and job manager tasks that run on pools created with the virtual machine configuration. The Batch service API provides a simple way to persist output from within the code that creates a task and serves as an alternative to the File Conventions library. You can modify your Batch client applications to persist output without needing to update the application that your task is running. For more information, see Persist task data to Azure Storage with the Batch service API. When do I use the File Conventions library to persist task output? Azure Batch provides more than one way to persist task output. The File Conventions is best suited to these scenarios: You can easily modify the code for the application that your task is running to persist files using the File Conventions library.

You want to stream data to Azure Storage while the task is still running. You want to persist data from pools created with either the cloud service configuration or the virtual machine configuration. Your client application or other tasks in the job needs to locate and download task output files by ID or by purpose. You want to view task output in the Azure portal. If your scenario differs from those listed above, you may need to consider a different approach. For more information on other options for persisting task output, see Persist job and task output to Azure Storage. What is the Batch File Conventions standard?

The Batch File Conventions standard provides a naming scheme for the destination containers and blob paths to which your output files are written. Files persisted to Azure Storage that adhere to the File Conventions standard are automatically available for viewing in the Azure portal. The portal is aware of the naming convention and so can display files that adhere to it.

The File Conventions library for . NET automatically names your storage containers and task output files according to the File Conventions standard. The File Conventions library also provides methods to query output files in Azure Storage according to job ID, task ID, or purpose.

For more information, see About the Batch File Conventions standard. Link an Azure Storage account to your Batch account. To persist output data to Azure Storage using the File Conventions library, you must first link an Azure Storage account to your Batch account. If you haven't done so already, link a Storage account to your Batch account by using the Azure portal: Navigate to your Batch account in the Azure portal.

Under Settings, select Storage Account. If you do not already have a Storage account associated with your Batch account, click Storage Account (None). Select a Storage account from the list for your subscription.

For best performance, use an Azure Storage account that is in the same region as the Batch account where your tasks are running. Persist output data. To persist job and task output data with the File Conventions library, create a container in Azure Storage, then save the output to the container.

Use the Azure Storage client library for . NET in your task code to upload the task output to the container. For more information about working with containers and blobs in Azure Storage, see Get started with Azure Blob storage using . NET. Warning. All job and task outputs persisted with the File Conventions library are stored in the same container. If a large number of tasks try to persist files at the same time, storage throttling limits may be enforced. Create storage container.

To persist task output to Azure Storage, first create a container by calling Cloud. Job. Prepare. Output. Storage. Async. This extension method takes a Cloud.

Storage. Account object as a parameter. It creates a container named according to the File Conventions standard,so that its contents are discoverable by the Azure portal and the retrieval methods discussed later in the article. You typically place the code to create a container in your client application — the application that creates your pools, jobs, and tasks. Cloud. Job job = batch. Client. Job. Operations. Create. Job(. . There are four predefined Task. Output. Kind types: Task.

Output, Task. Preview, Task. Log, and Task. Intermediate. You can also define custom categories of output. Adobe Media Encoder Red Frames Corners.

These output types allow you to specify which type of outputs to list when you later query Batch for the persisted outputs of a given task. In other words, when you list the outputs for a task, you can filter the list on one of the output types. For example, . For example, in the merge task of a movie rendering job, you could persist the fully rendered movie as a job output. When your job is completed, your client application can list and retrieve the outputs for the job, and does not need to query the individual tasks. Store job output by calling the Job. Output. Storage. Save.

Async method, and specify the Job. Output. Kind and filename: Cloud. Job job = new Job.

Output. Storage(acct, job. Id). Job. Output. Storage job. Output.

Storage = job. Output. Storage(linked. Storage. Account). await job. Output. Storage. Save. Async(Job. Output. Kind. Job. Output, .

This parameter allows you to later query for (list) a specific type of output. The Job. Output. Kind type includes both output and preview categories, and supports creating custom categories. Store task logs. In addition to persisting a file to durable storage when a task or job completes, you may need to persist files that are updated during the execution of a task — log files or stdout. For this purpose, the Azure Batch File Conventions library provides the Task.

Output. Storage. Save. Tracked. Async method. With Save. Tracked. Async, you can track updates to a file on the node (at an interval that you specify) and persist those updates to Azure Storage. Best Web Design Software For Beginners 2013 Chevy. In the following code snippet, we use Save. Tracked. Async to update stdout.

Azure Storage every 1. Time. Span stdout. Flush. Delay = Time. Span. From. Seconds(3). File. Path = Path. Combine(. Environment. Get. Environment.

Variable(. So give the file a moment to catch up. For example, you might have code that downloads data from Azure Storage and performs transformation or calculation on it.

The important part of this snippet is demonstrating how you can wrap such code in a using block to periodically update a file with Save. Tracked. Async. The node agent is a program that runs on each node in the pool and provides the command- and- control interface between the node and the Batch service.
