> Calcite 1.5.0 introduced the use of RelFactories to create the operators. In
> particular, RelFactories contains the factories for all the operators in the
> system. Although we can still implement old rules by providing each
> individual factory (the constructor is deprecated, but it won't be removed
> till Calcite 2.0.0 is out), new rules will only provide constructors based on
> RelFactories. Thus, we propose to migrate immediately to the new interface.
