Overview

Package storage provides S3-backed file transfer functionality for template provisioning.

This package implements multipart upload/download with progress tracking, resume capability, and checksum verification for large file transfers during template provisioning.

Package storage provides advanced storage integration for Prism.

This package implements high-performance storage solutions including FSx filesystems, S3 mount points, and comprehensive storage analytics for research workloads.

Analytics types

type TransferManager added in v0.5.7 

type TransferManager struct {
	// contains filtered or unexported fields
}

TransferManager manages S3 file transfers with progress tracking and resume capability

func NewTransferManager added in v0.5.7 

func NewTransferManager(s3Client *s3.Client, options *TransferOptions) *TransferManager

NewTransferManager creates a new S3 transfer manager

func (*TransferManager) CancelTransfer added in v0.7.7 

func (tm *TransferManager) CancelTransfer(transferID string) error

CancelTransfer cancels an in-progress transfer by its ID. It calls the stored cancel function which propagates cancellation to the underlying upload or download context. If the transfer does not exist or has already completed, this is a no-op (returns nil).

func (*TransferManager) DeleteObject added in v0.5.7 

func (tm *TransferManager) DeleteObject(ctx context.Context, bucket, key string) error

DeleteObject deletes an object from S3

func (*TransferManager) DownloadFile added in v0.5.7 

func (tm *TransferManager) DownloadFile(ctx context.Context, bucket, key, localPath string) (*TransferProgress, error)

func (*TransferManager) GetTransferProgress added in v0.5.7 

func (tm *TransferManager) GetTransferProgress(transferID string) (*TransferProgress, bool)

GetTransferProgress retrieves a snapshot copy of the current progress of a transfer. A copy is returned so callers can safely read fields without holding the lock.

func (*TransferManager) ListTransfers added in v0.5.7 

func (tm *TransferManager) ListTransfers() []*TransferProgress

ListTransfers returns snapshot copies of all active transfers. Copies are returned so callers can safely read fields without holding the lock.

func (*TransferManager) UploadFile added in v0.5.7
