Q. What is an append blob?

A. Azure storage has three types of blob:

  • Block blob - Aimed at streaming and storing of objects such as media files and documents. Sequentially accessed
  • Page blobs - Optimized for random reads and writes
  • Append blob - Same as a block blob except data can only be added to the end of the blob. Blocks elsewhere cannot be deleted nor modified. This is useful for log scenarios
