> To reduce round trips between the Client and Datanode for reading a block, we nee a new API to read.
> {code}
> Client -> block(offset, length) -> Datanode
> Client <- chunkN <- Datanode
> Client <- chunkN+1 <- Datanode
> ..
> Client <-chunkLast <- Datanode
> {code}
> This is using the ability of gRPC to send bidirectional traffic such that the server can pipeline the chunks to the client without waiting for ReadChunk API calls. This also avoids the client from creating multiple Chunk Stream Clients and should simplify the read path on the client side by a bit.
