Top down planner
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!

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
