Review comment:
Can you clarify in the documentation that batching is the default ?
Alternatively, wow about just having a method withoutBatching() that can be
used to disable batching ?

> 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.
