Review comment:
Ideally we would keep both sets of tests, one that relies on just the
table name, and one that sets the SELECT/INSERT statement. We can leave this
for a follow-up though if you file a jira and add a TODO

Review comment:
nit: looks like there's an extraneous whitespace change here.
Please update this docstring (and the Read counterpart) based on our change
to table_name/statement/query. It should point out that table_name is required
and statement/query are optional, but can be overriden

Review comment:
Assuming this is because of BEAM-10632? Let's add a TODO here so we
remember to remove it later
```suggestion
testCompile library.java.mockito_core
// TODO(BEAM-10632): remove this dependency
testCompile "org.checkerframework:checker-qual:3.5.0"

Review comment:
I don't think we need this task, Python is responsible for running the
expansion service from the compiled jar using subprocess.

Review comment:
I think the next improvement to SchemaIO/Provider should be to formally
differentiate read-only and write-only configuration, it's confusing to combine
them this way when it's not needed. The only place its _needed_ is in SQL, so
we should do it there.
(you don't need to do anything here, I'm just getting some thoughts out)
