… from Storage.reader For some scenarios, an external client needs the ability to manage buffer blocking itself. To support this, providing 0 to ReadChannel#setChunkSize will disable buffering allowing for client to avoid the need to alight multiple levels of buffer alignments. Because the buffering is disabled, that means reads can be much more variable in size and individually more impacted by small network latencies (with buffering these can be amortized by the buffer making followup read faster). This is considered advanced usage and will require more work from the client integrator.
