Review comment:
minor nitpick, can you rename this ? I was expecting this one to use
SpannerIO.readAll() from its name, also maybe worth to mention that it tests
the naive case.

> In 2.4.0, SpannerIO#read has been migrated to use batch API. The batch API
> provides abstractions to scale out reads from Spanner, but it requires the
> query to be root-partitionable. The root-partitionable queries cover majority
> of the use cases, however there are examples when running arbitrary query is
> useful. For example, reading all the table names from the
> information_schema.* and reading the content of those tables in the next
> step.
