> PutAzureBlobStorage_v12 currently uses the Azure Blob Storage default block 
> size of 4MB.  Azure Blob Storage has a maximum number of blocks of 50,000 per 
> blob.  Therefore, the largest file that PutAzureBlobStorage_v12 can currently 
> upload is 4MB * 50,000 = 200GB.  The service supports blocks up to 4,000MiB 
> for a total of 4,000MiB * 50,000 = 190.7TiB per blob, about 1,000x larger 
> than NiFi can currently upload.  The block size should be calculated 
> dynamically – or at least be configurable – to allow uploading files larger 
> than 200GB.
