2. Change Feed Replication<\/strong>: Online Copy Jobs use the \u201call version and delete change feed mode<\/a>\u201d to capture and replicate every update from the source container.<\/p>\n 3. Smart Resource Management<\/strong>: After completion, resources are automatically deallocated to optimize costs.<\/p>\n Before you begin, make sure your environment meets these prerequisites:<\/p>\n 2. Assign Permissions<\/strong>: Grant read permissions on the source account using a managed identity.<\/p>\n 3. Create the Copy Job<\/strong>: Run the following command to create the copy job<\/p>\n 4. Monitor Job Progress<\/strong>: Use Azure CLI or the portal to track status.<\/p>\n Key metrics:<\/p>\n 5. Complete the Job<\/strong>: Once all data is copied to the destination container, update your applications to use the destination container and then call the completion API. This crucial step ensures any remaining changes are drained from the source to the destination and deallocates resources, concluding the migration process with minimal downtime.<\/p>\n In the Azure portal, view progress in the Copy Job listing page<\/strong> with completion percentage.<\/p>\n Using CLI, the show command provides real-time updates.<\/p>\n Start leveraging the power of Online Copy Jobs in Azure Cosmos DB to seamlessly scale, optimize, and manage your data with minimal downtime. Whether expanding your data strategy, improving disaster recovery, or creating an isolated analytics container, Online Copy Jobs will help you achieve it efficiently.<\/p>\n For more information, explore the Azure Cosmos DB documentation on Online Container Copy<\/a> and start your journey toward hassle-free data migration today!<\/p>\n Tell us about your Azure Cosmos DB experience!
