Peter Bourgon on Gossip, Paxos, Microservices in Go, and CRDTs at SoundCloud

Peter Bourgon discusses his work at Weaveworks, discovering and imlemeting CRDTs for time-stamped events at Soundcloud, Microservices in Go with Go Kit and the state of package management in Go. Why listen to this podcast: - We’ve hit the limits of Moore’s law so when we want to scale we have to think about how we do communication across unreliable links between unreliable machines. - In an AP algorithm like Gossip you still make forward progress in case of a failure. In Paxos you stop and return failures. - CRDTs give us a rigours set of rules to accommodate failures for maps, sets etc. in communication that result in am eventually consistent system. - Go is optimised to readers/maintainers vs. making the programmers’ life easier. Go is closer to C than Java in that it allows you to layout memory very precisely, allowing you to, for example, optimise cache lines in your CPU. - Bourgon started a project called Go Kit, which is designed for building microservices in Go. It takes inspiration from Tiwtter’s Scala-based Finagle which solved a lot of Micoservice concerns. - Go has a number of community-maintained package managers but no good solution; work in ongoing to try and resolve this.
