I need some details @xhzengAIB

1. Are you using CoreData or Realm?

Could you give more details about what you are planning to do. Thanks!

Hi! @pepibumur
I'm doing a RSS App, this Entity(Article Model) have a field is readed.

1. I launched a network request, pull 100000 RSS articles（JSON array）.
2. I need to mark the 100000 RSS articles as readed.

My question is: CoreData how to deal with large amount of data? If there is need to article 10000000 input for persistence, that CoreData. What should I do?

@xhzengAIB you should do something like this:

SugarRecord.operation(SugarRecordStackType.SugarRecordStackTypeRealm, closure: { (context) -> () in
  let articles: [Article]? = Article.all().find(inContext: context)?
  context.beginWriting() // <- Notifying we're starting the edition
  for articleDict in articlesArray {
    let article: Article? = (articles.filter() { $0.articleID == articleDict["id"] }).first
    if article != nil {
      article!.read = true
    }
  }
  context.endWriting() // <- Notifying that we've finished the edition
})

Notice that instead of fetching articles filtering them by ID I fetch all of them and them filter the array using the filter method available in Swift arrays. @xhzengAIB

Hi! @pepibumur

This is the transaction processing CoreData?
