Updating blob Xxx moibusa com
Block blobs are comprised of blocks, each of which is identified by a block ID.
You create or modify a block blob by writing a set of blocks and committing them by their block IDs.
When a block blob upload is larger than the value in this property, storage clients break the file into blocks.
Block blobs include features that help you manage large files over networks.
With a block blob, you can upload multiple blocks in parallel to decrease upload time.
For any commit operation, if any block is not found, the entire commitment operation fails with an error, and the blob is not modified.
Any block commitment overwrites the blob’s existing properties and metadata, and discards all uncommitted blocks.
