Multipart Uploads

Welcome to our guide on optimizing your file uploads with multipart uploads. Let’s delve into the details and explore how multipart uploads can enhance the speed and efficiency of your data transfers.

Understanding Multipart Uploads

Multipart uploads revolutionize the way data is uploaded by enabling parallel uploading, significantly boosting speed and efficiency. Unlike traditional single uploads, multipart uploads divide large objects into smaller parts, making the process more manageable and robust. In case of failure during upload, only the failed parts need to be retried, eliminating the need to restart the entire upload process.

Determining When to Use Multipart Uploads

It’s recommended to opt for multipart uploads when dealing with large objects exceeding 100 mebibytes in size. Objects can be divided into a maximum of 10,000 parts, with each part ranging from 10 mebibytes to 50 gibibytes. This flexibility allows for efficient handling of data of varying sizes.

Automating Cleanup with Object Lifecycle Policies

Object lifecycle policies offer a convenient way to manage multipart uploads. You can set rules to automatically delete uncommitted or failed multipart uploads after a specified number of days, streamlining storage management and ensuring optimal resource utilization.

Performing Multipart Uploads

Using the Multipart Upload API

To initiate a multipart upload using the API, follow these steps:

1. Create Parts: Divide the object into smaller parts, ensuring each part meets the size requirements.
2. Initiate Upload: Make a create multipart upload API call to obtain an upload ID, marking the upload as active.
3. Upload Object Parts: Submit upload part requests for each part, receiving an entity tag value for each uploaded part.
4. Commit Upload: Finalize the upload by making a commit multipart upload request, allowing object storage to reconstruct the object from its constituent parts.

Using the Command Line Interface (CLI)

Performing multipart uploads via the CLI differs slightly:

1. Specifying Part Size: Specify the desired part size using the mandatory part size flag, allowing object storage to automatically split the object.
2. Setting Parallel Upload Count: Optionally, set the maximum number of parallel uploads allowed for optimal performance.

By leveraging multipart uploads, you can streamline your data transfer processes, enhance efficiency, and ensure seamless management of large objects. Whether using the API or CLI, incorporating multipart uploads into your workflow can greatly optimize your file uploading experience.
