Azure.Storage.Blobs.Specialized.AppendBlobClient
The AppendBlobClient allows you to manipulate Azure
Storage append blobs.
An append blob is comprised of blocks and is optimized for append
operations. When you modify an append blob, blocks are added to the
end of the blob only, via the AppendBlockAsync
operation. Updating or deleting of existing blocks is not supported.
Unlike a block blob, an append blob does not expose its block IDs.
Each block in an append blob can be a different size.
Beginning with x-ms-version 2022-11-02, the maximum append size is 100 MB.
For previous versions, the maximum append size is 4 MB.
Append blobs can include up to 50,000 blocks.
