>The code includes Apache Ignite as a parameter server. Is it possible to
make this independent of Ignite? I know that SSP is usually used in parameter
server ML settings, but I would like to not tie Ignite (another big dependency)
into the Flink codebase.
I propose the following then:
1. Move the code related to the parameter server (model + Ignite
implementation) currently in flink-core to a separate module.
2. Remove the parameter server startup code from the taskmanager.
This then implies that in order to use SSP and the parameter server the
following needs to be done in the user job code:
1. Include the parameter server module as dependency to the project.
2. Start and stop the parameter server before and after each job.
How does that look for you?
