Reference in a new issue
I've got a question: you separate header and a payload and then marshal the header.
I thought that the number of EC-encoded parts depends on binary size (
header_marshalled_size != payload_marshalled_size) but here you expect the header shards number is equal to payload shards number. How come?Size is not equal, but the number of shards is equal.
It follows, that the size of chunks are not equal.
