It is used prominently in Google Search, App Engine, Google Analytics, Google Earth and other applications. Quickstarts are provided to write and read data from Bigtable tables using the cbt tool or HBase shell. Key features include large storage capacity, integration with machine learning tools, high throughput, availability and scalability.
