Hi @kirankumar994, since FilePart.content() is part of your code, this is what needs to be changed to return ByteBuffers larger than 1024 bytes. Once you increase that, you should use less blocks to upload large files. For reference, within the SDKs we have a method that uploads a file as blocks which uses a default block size of 4MB (4,194,304 bytes).

Optionally, if you don't want to write you own implementation for uploading a file, you can always use BlobAsyncClient.uploadFromFileWithResponse which allows for you to pass BlobUploadFromFileOptions where you can configure the SDK to upload blocks of a certain size.

Marking as resolved as this is either a need to change your code to produce larger blocks or to migrate to the API within the SDK. Other than that, this is expected behavior by the service as 100,000 uncommitted blocks is an explicit limitation:

Hi @alzimmermsft ,

Could you please me how to increase filepart.content() to make larger chunks to return ByteBuffer larger than 1024 bytes with the above code? I have tried to increase, but it always emits 1024 bytes. Thank you so much in advance.

[alzimmermsft]

Unfortunately, I'm unable to provide a way to increase the output of FilePart.content() as that isn't part of SDK and I have no knowledge of how it works.

Okay, Thank you for your response @alzimmermsft .
