“Sometimes there’s a misconception that Genie is a job scheduling platform… Genie really represents our extraction layer, from what our computational resources are, to our end user jobs.”
Genie is an open-source tool that provides job and resource management for the Hadoop ecosystem in the cloud.
Distributed systems programming will always be a world of tradeoffs — there is no silver bullet in the future. But life can be made easier with tactics such as the actor pattern and the use of conflict-free replicated data types (CRDTs).
Caitie McCaffrey is a distributed systems engineer who currently works at Twitter. She previously worked on Halo 4 at Microsoft and 343 Industries. At QCon San Francisco, she will be hosting the track Taming Distributed Architecture.
