Bigtable is best thought of as an "event database". High reads, high writes, single index, accessible through the Hbase API. Cassandra and Hbase are similar technologies that are inspired by the original Bigtable paper.

One big benefit of Bigtable is its scalability. To scale up, you turn the 'scale' knob. By contrast, Cassandra and Hbase are headaches to scale (Apple has acquired Cassandra companies to aid in operation and scale).

Here's a couple of guys from Sungard, who scaled to about 3,000,000 writes per second with a couple weekends' worth of effort (something only few beyond the likes of Facebook, Netflix, and Apple can achieve) https://cloud.google.com/bigtable/pdf/SunGardCATCaseStudy.pd...

Hey. I'm one of the "guys from SunGard", although I'm no longer there. The longer version is this: https://cloud.google.com/bigtable/pdf/ConsolidatedAuditTrail... . A lot of it is related to the use case, but yeah, Bigtable handled pretty much whatever we wanted to throw at it. No other cloud provider can offer this sort of scale and performance right now without a ton of manual management or significant compromises, something that seems to have yet to sink in (although few companies need the scale we went up to).

It did take a lot more work than "a couple weekends" though :).
