----------------------------------------------------------
We cannot opt-out of the shading rules in the SQL module as we cannot leak
{{Guava}} to our users.
If a shaded version of {{Calcite}} which relocates {{Guava}} exists we should
use that (such a version does not seem to exist). Otherwise, since {{Calcite}}
is under {{Apache License 2.0}} we can shade it into our SQL module, using the
same relocation rules applied in {{beam-parent}}.

> {{guava}} is shaded by default in beam modules, while {{calcite}}(a
> dependency of SQL) includes {{guava}} which is not shaded. Below error is
