> 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.
