Explanation
Explanation/Reference: Cloud Bigtable 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.

It supports high read and write throughput at low latency, and it is an ideal data source for MapReduce operations.
