Links of the day 13 - 05 - 2015

Today's link 13/05/2015: lisp diff, hierarchical Erasure code, real time #bigdata requirements, 30PB #Ceph deployment
  • ydiff : a structural comparison tool for Lisp
  • Hierarchical Erasure Coding : cover two different approaches to erasure coding – a flat erasure code across JBOD, and a hierarchical code with an inner code and an outer code.
  • 8 system-level requirements : really good paper on the requirement for scalable robust real time data processing ( and why using DB or rule engine has certain limiations.
  • Ceph ~30PB Test Report : Benchmark at Cern , the interesting bit is that it show that Ceph still has quite a bit of runway on the perfomance side, not to mention managability in order to really scale. Which would match the openstack conf report that most deployment of such tech tend to be in small cluster.
