Applications that use Spanner for high throughput often need more than one gRPC channel in order to achieve the best possible performance. Having more than one channel both increases the number of concurrent streams that an application can have open at any time (the limit is 100 per gRPC channel), and distributes the load that is generated by the application across multiple Spanner frontends.
