This RPC API is Google's NoSQL Big Data database service. The Service name bigtable.googleapis.com is needed to create RPC client stubs and includes Marketing data, Financial data, Internet of Things and more. You can store the cluster's data on solid-state drives (SSD) or hard disk drives (HDD). Cloud Bigtable is ideal for storing very large amounts of single-keyed data with very low latency and supports high read and write throughput again at low latency, and it is an ideal data source for MapReduce operations. It powers many core Google services, including Search, Analytics, Maps, and Gmail. It is a sparsely populated table that can scale to billions of rows and thousands of columns, allowing you to store terabytes or even petabytes of data.
