Wei-Chiu Chuang updated HDDS-10338:
-----------------------------------
Target Version/s: 2.2.0
> Implement a Client Datanode API to stream a block
> -------------------------------------------------
>
> Key: HDDS-10338
> URL: https://issues.apache.org/jira/browse/HDDS-10338
> Project: Apache Ozone
> Issue Type: New Feature
> Components: Ozone Client, Ozone Datanode
> Reporter: Ritesh Shukla
> Assignee: Chung En Lee
> Priority: Major
> Labels: ozone-performance, pull-request-available
>
> 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.
