Sandesh commented on APEXCORE-467:
----------------------------------
[~pramod.immaneni]
I tried to make the BufferServer start on-demand when any operator needs to
send tuples to different containers (even during dynamic partitioning), but It
required a lot of changes.
Also looking at the Buffer Server code, it allocates most of the
resources(DataList) only when there is Publish/Subscribe request, so not much
resource are wasted to keep it running. Another point, there is a Jira to allow
users to bypass bufferserver, so for this jira "won't fix".
> BufferServer should not be deployed in the containers with only Output
> operators

> BufferServer is started in all the streaming containers, but it is not
> required in all the containers.
> For example, Containers with only Output operators or the containers with
> output ports which are not connected to ports outside the containers don't
> need BufferServer.
> During the operator deployment, it is assumed that BufferServer is already
> started in every container, that needs to be changed to address this issue.
