The QueryPartition class is a regular type that represents a single slice of a parallel SQL read.
Instances of QueryPartition are created by Client::PartitionQuery. Once created, QueryPartition objects can be serialized, transmitted to separate processes, and used to read data in parallel using Client::ExecuteQuery. If data_boost is set, those requests will be executed using the independent compute resources of Cloud Spanner Data Boost.
