Jonathan Ellis talks about Five Lessons in Distributed Databases

Notes on the talk…

1. If it’s not SQL it’s not a database. Watch, you’ll get to hear why… ha!

Then Jonathan covers the recent history (sort of recent, the last ~20ish years) of the industry and how we’ve gotten to this point in database technology.

1. It takes 5+ years to build a database.

Also the tens of millions of dollars with that period of time. Both are needed, in droves, time and money.

…more below the video.

1. The customer is always right.

Even when they’re clearly wrong, they’re largely right.

For number 4 and 5 you’ll have to watch the video. Lot’s good stuff in this video including comparisons of Cosmos, Dynamo DB, Apache Cassandra, DataStax Enterprise, and how these distributed databases work, their performance (3rd Party metrics are shown) and more details!
