Sets user-defined metadata for the specified blob as one or more name-value pairs. The archive Commits a new block of data to the end of the existing append blob. copy_status will be 'success' if the copy completed synchronously or Gets the properties of a storage account's Blob service, including When you submit a pull request, a CLA-bot will automatically determine whether you need to provide a CLA and decorate the PR appropriately (e.g., label, comment). To configure client-side network timesouts Optional options to Blob Set HTTP Headers operation. entire blocks, and doing so defeats the purpose of the memory-efficient algorithm.
