❔ Upload large files to azure storage!

Does anyone have a method that uploads large files to azure storage efficiently? I'm using

Azure.Storage.Blobs

Azure.Storage.Blobs

Here is the current method

public async Task<Uri?> UploadFileAsync(string containerName, string fileName, Stream stream,
        CancellationToken cancellationToken)
    {
        try
        {
            var containerClient = _blobService.GetBlobContainerClient(containerName);
            await containerClient.CreateIfNotExistsAsync(cancellationToken: cancellationToken);
            var blobClient = containerClient.GetBlockBlobClient(fileName);
            
            var options = new BlobUploadOptions
            {
                TransferOptions = new StorageTransferOptions
                {
                    MaximumConcurrency = 16, // Adjust the concurrency level as needed
                    MaximumTransferSize = 4 * 1024 * 1024, // 4MB chunk size
                },
            };

            await blobClient.UploadAsync(stream, options, cancellationToken);
            return blobClient.Uri;
        }
        catch (Exception ex)
        {
            return null;
        }
    }

public async Task<Uri?> UploadFileAsync(string containerName, string fileName, Stream stream,
        CancellationToken cancellationToken)
    {
        try
        {
            var containerClient = _blobService.GetBlobContainerClient(containerName);
            await containerClient.CreateIfNotExistsAsync(cancellationToken: cancellationToken);
            var blobClient = containerClient.GetBlockBlobClient(fileName);
            
            var options = new BlobUploadOptions
            {
                TransferOptions = new StorageTransferOptions
                {
                    MaximumConcurrency = 16, // Adjust the concurrency level as needed
                    MaximumTransferSize = 4 * 1024 * 1024, // 4MB chunk size
                },
            };

            await blobClient.UploadAsync(stream, options, cancellationToken);
            return blobClient.Uri;
        }
        catch (Exception ex)
        {
            return null;
        }
    }

it looks fine blob uploading is slow

This should work for large files as well and you can get the progress also from IProgress that UploadAsync() uses. Are you facing any issue??

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
