Looks like CloudBlob has 3 subclasses you can use to get data in and out of Azure Storage. Here's the (very sparse) documentation:

  • Microsoft.WindowsAzure.Storage.Blob.CloudBlockBlob

    • Represents a blob that is uploaded as a set of blocks.

  • Microsoft.WindowsAzure.Storage.Blob.CloudAppendBlob:

    • Represents an append blob, a type of blob where blocks of data are always committed to the end of the blob.

  • Microsoft.WindowsAzure.Storage.Blob.CloudPageBlob

    • Represents a Microsoft Azure page blob.

I've been using CloudBlockBlob to upload/download pdfs and images, and everything seems to be working. I can't seem to find a page that explains what these classes do.

Under what circumstances should I use CloudAppendBlob and CloudPageBlob?

  • CloudAppendBlob UploadFromByteArray Hangs or Thread Does not Return but file is fully written to the blob store. single-writer scenarios. This is the question and doc you are looking for. Microsoft.WindowsAzure.Storage.Blob.CloudAppendBlob – Sql Surfer Jul 03 '19 at 13:12

Found the page I was looking for: https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blobs-introduction

  • CloudBlockBlob:

    • Block blobs are ideal for storing text or binary files, such as documents and media files.

  • CloudAppendBlob:

    • Append blobs are similar to block blobs in that they are made up of blocks, but they are optimized for append operations, so they are useful for logging scenarios.

  • CloudPageBlob:

    • Page blobs can be up to 1 TB in size, and are more efficient for frequent read/write operations. Azure Virtual Machines use page blobs as OS and data disks.
