Ritesh Shukla updated HDDS-10338:
---------------------------------
Description:
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.
