  • I am using docker-compose to stand dataflow server on an openstack machine with 32 gb ram I have one deployed stream, and 4 undeployed streams. I have not set deployer properties inside docker-compose.yml

When running

docker stats datalow-server

I see : memory usage as  26 GB/32 GB

I suppose that I need to use JVM restriction by using the property

spring.cloud.deployer.local.javaOpts

I believe you are using the local SCDF server implementation.

What is the recommended -Xmx and -Xms values to be used for Data Flow server

There are no recommended values as it heavily depends on what/how many apps you try to deploy in the same instance. For SCDF local, it launches all the stream app instances in the same VM/container/machine so it is shared by the running apps.
