Azure Block Blob 和 Page Blob 的区别? [英] Differences between Azure Block Blob and Page Blob?
问题描述
当我最近开始使用 Windows Azure 时，我遇到了一种情况，在 Block Blob 和页面 Blob.我目前正在将一些文本、csv 或 dat 文件上传到 blob 存储，然后使用我的 C# 程序为其执行 MapReduce 程序.是的，我已经阅读了一篇文章.
As I recently started mingling around with Windows Azure, I've came up to a situation where, which one to go for between the Block Blob & Page Blob. I'm currently in progress of uploading some text, csv or dat files to a blob storage and then do a MapReduce program for it using my C# program. Yes I've gone through an article.
但无法从他们那里得到一个明确的想法.简而言之，Block Blob vs Page Blob.任何帮助将不胜感激.
But couldn't get a clear idea from them. To cut short, Block Blob vs Page Blob. Any help would be appreciated.
推荐答案
差异在 msdn 上有很好的记录，这里.特尔；博士:
The differences are very-well documented on msdn, here. TL;DR:
- 块 blob 用于您的离散存储对象，例如 jpg、日志文件等，您通常将它们视为本地操作系统中的文件.最大限度.大小
200GB4.77TB.仅限常规(非高级)存储空间. - 页 Blob 用于随机读/写存储，例如 VHD(实际上，页 Blob 用于 Azure 虚拟机磁盘).最大限度.8TB 大小.受普通存储和高级存储支持.
- Block blobs are for your discrete storage objects like jpg's, log files, etc. that you'd typically view as a file in your local OS. Max. size
200GB4.77TB. Regular (non-Premium) storage only. - Page blobs are for random read/write storage, such as VHD's (in fact, page blobs are what's used for Azure Virtual Machine disks). Max. size 8TB. Supported by both regular and Premium Storage.
注意:高级页面 Blob 具有特定的大小(与常规页面 Blob 不同，后者可以是任何大小，最高可达 8TB).
Note: Premium page blobs have specific sizings (unlike regular page blobs, which can be any size up to 8TB).
- 32GB
- 64GB
- 128GB
- 512GB
- 1024GB
- 2048GB
- 4096GB
高级存储提供有保证的 IOPS 和吞吐量，具体取决于所选的页面 blob 大小(从 120 IOPS+25MB/s @ 32GB 到 7500 IOPS+250MB/s @ 2048GB & 4096GB).此处记录了有关 IOPS+吞吐量的具体细节.
Premium storage provides guaranteed IOPS and throughput, depending on the page blob size chosen (from 120 IOPS+25MB/s @ 32GB to 7500 IOPS+250MB/s @ 2048GB & 4096GB). Specific details around IOPS+throughput details are documented here.
