                newValue = Arrays.copyOfRange(buffer.array(), buffer.position(), buffer.limit());
            }
            BlobAsync blob = new BlobAsync(blobDir);
            blob.truncate(txn.getTransaction(), 0).get();
            blob.write(txn.getTransaction(), 0, newValue).get();
        } else {
