— If you trigger from API, you can just spin up HTTP from node

— 

Four hourly triggers, you can use cron / Task Scheduler in your system, OR you can keep node running and use npmjs.org/cron

— For the cron system I already choose for npmjs.org/cron

— Ahh, alright

— So basic structure:

mainProcedure() {
  setSomeRedisKeys(getDataFromMongo())
  cleanVarnishCache()
}

api.on('trigger', mainProcedure)

cron(mainProcedure)

— 

getData()
  .then(reduceData)
  .then(writeDatatoRedis)


Might be the preferred way

— Separating each process so you can switch mongo or redis independently

— Any external thing is a dependency, so they should be decoupled

— While the reducing operation shouldn't know about either mongo nor redis

— Hey guys, do you know where or have a function which removes one structure from another? Some kind of Object1 - Object2 = reduced Object1
