Differences between Azure Block Blob and Page Blob? (6 个回答)

已关闭 1 年前。

看起来像CloudBlob有 3 个子类，可用于将数据传入和传出 Azure 存储。这是(非常稀疏的)文档:

• 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.

我一直在使用CloudBlockBlob上传/下载 pdf 和图像，一切似乎都正常。我似乎找不到解释这些类的作用的页面。

什么情况下应该使用CloudAppendBlob和CloudPageBlob ？

找到了我要找的页面: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.
