Append blob support for Azure Data Lake Storage is now in limited public preview
发布日期：二月 05, 2021
Append blobs allow users to append data to the end of a blob or file quickly and 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. With this preview, applications can use create append blobs in these accounts also and write to them using Append Block operations. These append blobs can be read by using existing Blob APIs and Azure Data Lake Storage APIs. To learn more, please read the documentation on Append Blob.
Data storage prices for append blobs are the same as those called out on Azure Data Lake Storage pricing page. Transactions on append blobs will be priced as Write operations.
Append blob support for Azure Data Lake Storage is now available in preview globally in all Azure regions. To enroll in the limited public preview, please complete this form.
