What's the alternative to GridAttributesTopologySpi in GridGain 6 (open source version)

Question

We're migrating an application from an older gridgain 4 codebase to gridgain 6. In the old application, we partitioned the nodes based on the grid attribute key "com.mycompany.workgroup" . The new release doesn't have a topologySpi configuration property or GridAttributesTopologySpi .

1. What is the recommended approach or alternative?

2. Do any of the supplied examples address my requirement? Maybe I missed something when browsing through them.

Thanks

The alternative is to use GridProjection, like so

Grid grid = GridGain.grid();

GridProjection prj = grid.forAttribute("com.mycompany.workgroup", "workers");

GridComputeTaskFuture<?> fut = prj.compute().execute(new MyTask());

// Synchronous wait.
prj.get();
