Personalisering av tv.nrk.no

Editor's Notes

  1. Hva er personalisering for NRK. Favoritter, mine programmer. Analyse, kobles til innholdsplakat.
  2. 20-40K API requests / minutt Median 13-15ms 95 persentil 150-200ms 99 persentil 600-800ms TV, Radio og Klipp. Read only
  3. Ingen «kontroll» på når data endres. Web, App,
  4. 100K samtidige seere on-demand Oppdateringsfrekvens Play start, delayed Hvert 2 minutt Pause Onbeforeunload Program slutt ca 55K request / minutt Separate API kall / Resources Berikelse av eksisterende kall Mengden data øker over tid, hvem er master.
  5. Presentasjon av personaliserte data Synkronisering mellom to datasentre Caching Skalering 8 fallacies of distributed computing The network is reliable. Latency is zero. Bandwidth is infinite. The network is secure. Topology doesn't change. There is one administrator. Transport cost is zero. The network is homogeneous.
  6. Command Query Responsibility Segregation Naturlig med forskjellig skriveløp, gir mulighet å skalere de to individuelt.
  7. Queue based load leveling
  8. Ujevn ytelse
  9. Competing consumers. - mulighet å øke ytelsen på skrivelaget ved behov. Reliability, feiler en så fortsetter resten. En treg melding vil ikke forstyrre resten.
  10. Publish subscribe – fra observer. Her melding dupliseres og behandles individuelt.
  11. Content based router - filtrering
  12. Command Query Responsibility Segregation Naturlig med forskjellig skriveløp, gir mulighet å skalere de to individuelt.
  13. Partitioning component of Amazon's storage system Dynamo[4][5] Data partitioning in Apache Cassandra[6] Data Partitioning in Voldemort[7] Akka's consistent hashing router[8]
  14. Forbedringer: Egen kø hvis noe må sendes på nytt for en worker, topic sender alltid alt til alle. Cassandra – data senter aware storage. Eventhub -> Stream analytics – multiple datacenter
