Build intelligent apps with a single database that brings together relational, graph, key value, and search. No maintenance windows mean uninterrupted mission-critical apps.
Google recently unveiled one of their crown jewels of system infrastructure: Borg, their cluster scheduler. This prompted me to re-read the Mesos and Omega papers, which deal with the same topic. I thought it'd be interested to do a compare and contrast of these systems. Mesos gets credit for the groundbreaking idea of two-level scheduling, Omega improved upon this with an analogy from databases,
In Taming The Long Latency Tail we covered Luiz Barrosoâs exploration of the long tail latency (some operations are really slow) problems generated by large fanout architectures (a request is composed of potentially thousands of other requests). You may have noticed there werenât a lot of solutions. Thatâs where a talk I attended, Achieving Rapid Response Times in Large Online Services (slide deck

Paxos Made Live &ndash An Engineering Perspective Tushar Chandra, Robert Griesemer, and Joshua Redstone Abstract We describe our experience building a fault-tolerant data-base using the Paxos consensus algorithm. Despite the existing literature in the field, building such a database proved to be non-trivial. We describe selected algorithmic and engineering problems encountered, and the solutions
