Hello,
Apache Ignite currently employs the top-down approach. Take a look at
this package [1].
The only documentation about the top-down I have seen so far can be
found in this javadoc [2]
You can also read several discussions on the devlist about this topic
[3], [4]

Hello friends,
What is the best resource for learning how to use the top down planner flag
in calcite? Are there any open source projects that use that capability
that I can study to learn more? I would like to see examples of projects
that use this capability to "distribute" a plan over multiple nodes using
traits like distribution / collation etc.
Regards!
