    How to move links to WorldCat?

  • Pretend you are a Connexion ClientProgram to:Log inSearch for recordVerify heading hasnt changedInsert authorized formAdd linkDo replace

  • Then just replace 26 million recordsEach update takes two transactionsRetrieve the recordReplace the recordIf it takes 2 seconds/update52,000,000 seconds~ 2 years

  • But, we can run multiple clientsConnexion can handle 40+ of these clients~ 20 records/secondOffline processing has limited capacityRun 32 clients for 12 hours for 16 updates/second~700,000 overnightUp to a million/day3 million/week2-3 months elapsed time
