Review comment:
String comparison is vulnerable. Another way to run a strict rule(if you
want) is, call
[BeamQueryPlanner.convertToBeamRel](https://github.com/apache/beam/blob/master/sdks/java/extensions/sql/src/main/java/org/apache/beam/sdk/extensions/sql/impl/BeamQueryPlanner.java#L116),
and inspect the RelNode hierarchy.

> Support optimized logical plan
> ------------------------------
>
> Key: BEAM-4388
> URL: https://issues.apache.org/jira/browse/BEAM-4388
> Project: Beam
> Issue Type: Sub-task
> Components: dsl-sql
> Reporter: Kai Jiang
> Assignee: Kai Jiang
> Priority: Major
> Time Spent: 5h 10m
> Remaining Estimate: 0h
>
> Before converting into Beam Pipeline physical plan, logical plan should be
> optimized and it will be super helpful for efficiently executing Beam
> PTransforms pipeline.
> Calcite has two ways for optimizing logical plan (HepPlanner and
> VolcanoPlanner). We can support VolcanoPlanner first and apply calcite
> builtin optimize rules (like
> FilterJoinRule.FILTER_ON_JOIN) to sql query optimize plans.
