Review comment:
The module `shardingsphere-infra-optimize` can be regarded as an adaptor
of calcite, and cannot optimize the join operator which can be pushdown to the
sharding database. `shardingsphere-infra-optimizer` module does not depend on
the `shardingsphere-infra-executor` which is different from
`shardingsphere-infra-optimize` too. The `shardingsphere-infra-executor` will
depend on the `shardingsphere-infra-optimizer` for the execution of the
physical plan.
