> Avoid buffer copies while submitting client requests in Ratis
> -
>
> Key: HDDS-2169
> URL: https://issues.apache.org/jira/browse/HDDS-2169
> Project: Hadoop Distributed Data Store
>  Issue Type: Improvement
>Reporter: Shashikant Banerjee
>Assignee: Tsz-wo Sze
>Priority: Major
>  Labels: pull-request-available
>  Time Spent: 4.5h
>  Remaining Estimate: 0h
>
> Currently, while sending write requests to Ratis from ozone, a protobuf 
> object containing data encoded  and then resultant protobuf is again 
> converted to a byteString which internally does a copy of the buffer embedded 
> inside the protobuf again so that it can be submitted over to Ratis client. 
> Again, while sending the appendRequest as well while building up the 
> appendRequestProto, it might be again copying the data. The idea here is to 
> provide client so pass the raw data(stateMachine data) separately to ratis 
> client without copying overhead. 
>  
> {code:java}
> private CompletableFuture sendRequestAsync(
> ContainerCommandRequestProto request) {
>   try (Scope scope = GlobalTracer.get()
>   .buildSpan("XceiverClientRatis." + request.getCmdType().name())
>   .startActive(true)) {
> ContainerCommandRequestProto finalPayload =
> ContainerCommandRequestProto.newBuilder(request)
> .setTraceID(TracingUtil.exportCurrentSpan())
> .build();
> boolean isReadOnlyRequest = HddsUtils.isReadOnly(finalPayload);
> //  finalPayload already has the byteString data embedded. 
> ByteString byteString = finalPayload.toByteString(); -> It involves a 
> copy again.
> if (LOG.isDebugEnabled()) {
>   LOG.debug("sendCommandAsync {} {}", isReadOnlyRequest,
>   sanitizeForDebug(finalPayload));
> }
> return isReadOnlyRequest ?
> getClient().sendReadOnlyAsync(() -> byteString) :
> getClient().sendAsync(() -> byteString);
>   }
> }
> {code}

Please ignore the previous Jenkins build.  It was testing an old patch 
(o2169_20190923.patch, just removed).

> Avoid buffer copies while submitting client requests in Ratis
> -
>
> Key: HDDS-2169
> URL: https://issues.apache.org/jira/browse/HDDS-2169
> Project: Hadoop Distributed Data Store
>  Issue Type: Improvement
>Reporter: Shashikant Banerjee
>Assignee: Tsz-wo Sze
>Priority: Major
>  Labels: pull-request-available
>  Time Spent: 1h 40m
>  Remaining Estimate: 0h
>
> Currently, while sending write requests to Ratis from ozone, a protobuf 
> object containing data encoded  and then resultant protobuf is again 
> converted to a byteString which internally does a copy of the buffer embedded 
> inside the protobuf again so that it can be submitted over to Ratis client. 
> Again, while sending the appendRequest as well while building up the 
> appendRequestProto, it might be again copying the data. The idea here is to 
> provide client so pass the raw data(stateMachine data) separately to ratis 
> client without copying overhead. 
>  
> {code:java}
> private CompletableFuture sendRequestAsync(
> ContainerCommandRequestProto request) {
>   try (Scope scope = GlobalTracer.get()
>   .buildSpan("XceiverClientRatis." + request.getCmdType().name())
>   .startActive(true)) {
> ContainerCommandRequestProto finalPayload =
> ContainerCommandRequestProto.newBuilder(request)
> .setTraceID(TracingUtil.exportCurrentSpan())
> .build();
> boolean isReadOnlyRequest = HddsUtils.isReadOnly(finalPayload);
> //  finalPayload already has the byteString data embedded. 
> ByteString byteString = finalPayload.toByteString(); -> It involves a 
> copy again.
> if (LOG.isDebugEnabled()) {
>   LOG.debug("sendCommandAsync {} {}", isReadOnlyRequest,
>   sanitizeForDebug(finalPayload));
> }
> return isReadOnlyRequest ?
> getClient().sendReadOnlyAsync(() -> byteString) :
> getClient().sendAsync(() -> byteString);
>   }
> }

[~msingh], thanks for taking a look.  The patch does apply.  Have you tried it?

Anyway, I just have submitted a pull request 
https://github.com/apache/hadoop/pull/1517

Sure, let's fix it in a separated JIRA.
