How to send large file as chunked requests under Resumable Upload in GCS if the chunk gets interrupted?

QUESTION

How to send large file as chunked requests under Resumable Upload in GCS if the chunk gets interrupted?

Asked 2020-Jul-19 at 18:27

Background

I am working on a project that creates an abstractions on top cloud storage and buckets. However, I had a problem of figuring out how to best support sending large files for GCS. We need the ability to send a large file in chunks, and we want to have control over the buffer/stream being sent in a chunk.

S3 has multipart upload, which allows us to send file in chunks in parallel. Unfortunately, GCS does not support this, they have composite objects which allows us to send files in parallel. However, composite objects come with various limitation. For example, unable to use customer-side encryption, MD5 digest, retention policy, having to do the temporary files clean up manually, etc. which are problematic because we want to support those things.

Resumable Upload

From documentation, the recommended way of sending a large file on GCS is via resumable uploads. Our use case would be sending a large file of unknown size in buffered chunks given that we know the size of each chunk and whether a chunk is a last part. From my understanding, the ideal case for this would be sending the first N-1 chunks with content-range=[offset-(offset+chunkSize)]/* with variable chunkSize and sending the last chunk as content-range=[offset-(offset + remainingSize)]/[TOTAL_SIZE].

My question is, what if a chunk upload gets interrupted?

What does it mean to resume an interrupted upload of a chunk? Do we send the remaining bytes of the current chunk (content-range=[lastByte-(chunkSize-lastByte)]/*) or do we send it together with the next chunk (content-range=[lastByte-(chunkSize-lastByte)+chunkSize]/*)?

Also, there is a limitation for resumable upload where each chunk must be multiple of 256KB. Does it mean an interrupt would make it impossible to keep the chunk in sync? So instead of having an expectation of having regular content-range for the chunks content-range=[offset-(offset+chunkSize)]/*, will an interrupt in resumable upload cause the remaining chunks to be sent dynamically until the last chunk?

Thank you so much.

What does it mean to resume an interrupted upload of a chunk? Do we send the remaining bytes of the current chunk (content-range=[lastByte-(chunkSize-lastByte)]/) or do we send it together with the next chunk (content-range=[lastByte-(chunkSize-lastByte)+chunkSize]/)?

It depends. There is no requirement to make all the chunk sizes the same, nor to make up your mind about them at the beginning of the upload, nor to remember what chunks you sent. As you note below there is a requirement to send all but the last chunks in sizes that are multiples of 256KiB.

To answer your question: if (chunkSize-LastByte) is a multiple of 256KiB, you could send that as a new chunk, or you may need to send the bytes from lastByte to lastByte + N * 256KiB

Also, there is a limitation for resumable upload where each chunk must be multiple of 256KB. Does it mean an interrupt would make it impossible to keep the chunk in sync?

No. What it means is that as you resume the upload the chunk boundaries may need to change.

In practice I think GCS always commits in boundaries of 256KiB, but I do not believe there is any guarantee that it will always do so.

I usually use vuex to manage variables that I will be using in multiple components and like the error says, load them in the various components using the computed properties. Then use the mutations property of the store object to handle changes
