> 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.
