ChunkedUpload

ChunkedUpload refers to a method of transferring large files over a network by dividing them into smaller, manageable pieces called "chunks." Instead of sending the entire file in a single request, the file is broken down into sequential chunks, and each chunk is uploaded independently. This approach offers several advantages, particularly for large files or unstable network connections.

One of the primary benefits of chunked uploads is improved reliability. If a connection drops during the upload process, only the last uploaded chunk needs to be re-sent, rather than the entire file. This significantly reduces the time and bandwidth wasted due to interruptions. Furthermore, chunked uploads can provide a better user experience by allowing for progress indication. Users can see how much of the file has been uploaded and estimate the remaining time, even if the total file size is very large.

The server-side implementation of chunked uploads typically involves mechanisms to reassemble these chunks in the correct order once all have been received. This often involves using unique identifiers for each upload session and metadata associated with each chunk to ensure proper reconstruction. Many modern web applications and cloud storage services utilize chunked uploads to handle the transfer of large documents, videos, or backups efficiently.
