Each request represents an instruction for the deployment system to carry out a defined set of actions, collectively referred to as a <strong>deployment operation<\/strong>.<\/p>\n<p>The operation associated with a request depends primarily on the API used to initiate it and, in some cases, its parameters. Internally, the deployment pipeline models its work as a series of deployment operations derived from an API called and its arguments.<\/p>\n<p>For example, <a href=\"https:\/\/learn.microsoft.com\/uwp\/api\/windows.management.deployment.packagemanager.movepackagetovolumeasync\">PackageManager.MovePackageToVolumeAsync()<\/a> submits a request to perform a <strong>Move Package<\/strong> operation. In most cases, method names serve as a clear indicator of the deployment operation being requested.<\/p>\n<p>Some operations may be requested through multiple APIs. For instance:<\/p>\n<ul>\n<li><a href=\"https:\/\/learn.microsoft.com\/uwp\/api\/windows.management.deployment.packagemanager.stagepackageasync\">PackageManager.StagePackageAsync()<\/a><\/li>\n<li><a href=\"https:\/\/learn.microsoft.com\/uwp\/api\/windows.management.deployment.packagemanager.stagepackagebyuriasync\">PackageManager.StagePackageByUriAsync()<\/a><\/li>\n<\/ul>\n<p>have different method names and parameter sets, yet both result in a deployment request to perform a <strong>Stage Package<\/strong> operation.<\/p>\n<h1>Deployment Operation<\/h1>\n<p>Deployment supports dozens of operations, including:<\/p>\n<ul>\n<li>Add Package<\/li>\n<li>Stage Package<\/li>\n<li>Register Package<\/li>\n<li>Remove Package<\/li>\n<li>Provision Package<\/li>\n<li>Deprovision Package<\/li>\n<li>Move Package<\/li>\n<li>Repair Package<\/li>\n<li>Reset Package<\/li>\n<li>Add Volume<\/li>\n<li>Remove Volume<\/li>\n<li>&#8230;more&#8230;<\/li>\n<\/ul>\n<p>You&#8217;ll see references to deployment operations throughout deployment logs and telemetry.<\/p>\n<p>The list of supported operations has grown steadily over time, as new servicing and management behaviors have been introduced. Most notably, this occurs when new operations and scenarios don&#8217;t naturally align with existing operations.<\/p>\n<h1>Deployment Request and Queue<\/h1>\n<p>A <strong>deployment request<\/strong> consists of a <strong>deployment operation<\/strong>, the input parameters provided with the requested operation, the caller&#8217;s user context, security context and other operational properties.<\/p>\n<p>Deployment requests are added to an in-memory priority queue (aka the <strong>deployment queue<\/strong>) in the deployment engine. Because deployment is multithreaded, multiple requests can be dequeued and processed in parallel, subject to concurrency controls where required.<\/p>\n<p>For example, if a Repair Package operation is in progress for Contoso.Parts_1.2.3.4_x64__1234567890abc, a Move Package request for the same package can be submitted. The Move request will be enqueued, but it won&#8217;t be dequeued for execution until the Repair operation completes.<\/p>\n<h1>Concurrency<\/h1>\n<p>Concurrency constraints may apply to an entire deployment request (as in the Repair\/Move example) or to specific portions of the work required to process the request. For instance, <a href=\"https:\/\/devblogs.microsoft.com\/insidemsix\/there-is-no-install-its-stage-and-register\/\">as previously mentioned<\/a> an Add Package operation can involve staging the package&#8217;s payload. Deployment supports a limited number (N) of concurrent staging activities (such as downloading package content from a network source). The value of N depends on system configuration, hardware capacity, current system activity and other factors.<\/p>\n<p>If N staging operations are already in progress, additional requests are accepted and processed, but any work requiring staging will be throttled until one of the active operations completes its staging work.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The PackageManager API submits requests to the deployment engine for processing.
