spring cloud dataflow multiple instances of processor in one stream

I'm new to spring cloud dataflow. I'm wondering if it is possible to have multiple instances of a processor in one stream.

For example

source | processor | sink

Can I configure it so that there are 2 instances of the processor app both subscribe the source in a round robin fashion and pipe the output to sink?

I know it is possible with 2 streams and named destination, but I'm wondering if it is possible to achieve this with 1 stream definition but perhaps with some properties?

Solution

  • Yes, that's the general idea. Use the deployer property count for the processor app. Look on the data flow dashboard, deploy screen, under generic deployer properties.
