Use this operation to upload a chunk or portion of the file data to the ObjectStore. You can also verify the file integrity of each chunk or the complete file in the last chunk using Secure Hash Algorithm (SHA) - 256 cryptographic hash function. For more information, see File Integrity Check.
Before you run this operation, make sure to initiate the upload session to ObjectStore. For details, see Initiate an Upload Session to ObjectStore.
