BatchReadOnlyTransaction is a ReadOnlyTransaction that allows for exporting arbitrarily large amounts of data from Cloud Spanner databases. BatchReadOnlyTransaction partitions a read/query request. Read/query request can then be executed independently over each partition while observing the same snapshot of the database.
ReadOnlyTransaction provides a snapshot transaction with guaranteed consistency across reads, but does not allow writes. Read-only transactions can be configured to read at timestamps in the past.
