Types

type ChunkUploader 

type ChunkUploader interface {
	// Queries for blocks that have already been uploaded.
	CompletedChunks(context.Context, ...ChunkUploaderOption) (any, error)

	// CompletedChunks(context.Context, ...chunkUploaderOption) (any, error)
	// Generate uploadID for uploaded files
	NewMultipartIdentifier(context.Context, ...ChunkUploaderOption) (string, error)

	// Generate URLs for uploading files
	GenMultipartSignedURL(context.Context, ...ChunkUploaderOption) (string, error)

	// After all the chunks are uploaded, this interface is called and the backend merges the files.
	Complete(context.Context, ...ChunkUploaderOption) error

	// To stop the upload, the user needs to destroy the chunked data.
	Abort(context.Context, ...ChunkUploaderOption) error

	// IncompleteUpload returns the number of times an object does not have a complete upload. Ideally,
	// it is guaranteed that there is only one uploadid per object.
	// If there is more than one uploadid, return the latest one.
	IncompleteUpload(context.Context, ...ChunkUploaderOption) (string, error)
}

Uploading files in chunks. 1. Get completed blocks 2. if there is no unique uploadid, you need to request a unique uploadid 3. request the upload file URL 4. Upload the file via the URL 5. Update the information of the uploaded block 6. merge files
