Append blob support in Azure Data Lake Storage is now generally available
Published date: 06 May, 2021
Append blobs provide a simple and effective way of adding new content to the end of a file or blob when the existing content does not need to be modified. This makes append blobs great for applications such as logging that need to add information to existing files efficiently and continuously. Until now, only block blobs were supported in Azure Data Lake Storage accounts. Applications can now also create append blobs in these accounts and write to them using Append Block operations. These append blobs can be read using existing Blob APIs and Azure Data Lake Storage APIs. To learn more, please read the documentation on append blobs.
Data storage prices for append blobs are the same as those called out on Azure Data Lake Storage pricing page. Append Block operations will be priced as Write operations.
