Recently, during a project that involved downloading a file from AWS S3 using C#, I discovered there were several ways to accomplish this task. In particular, I had three methods at my disposal:
Intrigued by these options, I decided to delve deeper and consult our trusty friend Google Bard for insights. The quest was to determine which method would emerge as the most efficient and scalable solution for our needs.
According to Google Bard, it became evident that the
TransferUtility.DownloadAsync method was a notable choice. The
TransferUtility.DownloadAsync method is designed to be more efficient and scalable than the
TransferUtility.DownloadAsync method is more efficient and more scalable because it uses a background thread pool to download the file. This means that the download can be performed in the background, without blocking the main thread. This can improve performance, especially for large files.
TransferUtility.DownloadAsync method is also more scalable because it can handle multiple downloads simultaneously. This means that it can be used to download files from Amazon S3 in parallel, which can improve performance for applications that need to download a large number of files.
GetObjectAsync methods do not use a background thread pool, so they are less efficient and less scalable. They also do not support resumable downloads, which can make them less reliable.
Here is a table that summarizes the differences between the
TransferUtility.DownloadAsync method and the
|Purpose||Downloads a single file||Downloads a single file||Downloads a single file or a directory|
|Argument||Name of the file||Name of the object||Name of the object|
|Return value||Task object||Stream object||IAmazonS3Object object|
|Efficiency||More efficient||Less efficient||Less efficient|
|Scalability||More scalable||Less scalable||Less scalable|
|Resumable downloads||Supported||Not supported||Not supported|
|Uses a background thread pool||Yes||No||No|
|Supports multiple downloads simultaneously||Yes||No||No|
|Supports resumable downloads||Yes||No||No|
While I haven’t directly examined the C# code from the AWS SDK, I believe this result from Google Bard provides valuable insights. I will update this blog post if I get new findings.
In my use case, where I only need to download a single file, I opted for
TransferUtility.DownloadAsync. It’s simpler, resulting in a more concise code with fewer lines.

Having too many unused or underused indexes on a table can slow down write and update operations in your PostgreSQL database, making it crucial to regularly identify and manage them for optimal performance.
