Understanding the impact of field level translation in Sanity

Last updated: Feb 8, 2024
Hi, I'm researching ways to Localize content in Sanity and in the Sanity docs I read that Portable text shouldn't be used with field level translation. Can someone help explaining me why thats the case and what happens if I do use it?

You eat through your attribute limit and end up getting to a point where your content is stuck unless you run a heavy duty migration.

hey, thanks. it's not very clear to me: does creating seperate documents uses less attributes than adding two portable text fields in one document?

Document level translation means that all translations use the same structure and therefore generate fewer paths. Here’s a super simple example:
Document level (multiple documents but they all use this structure):

{
  name,
  content: {
    //all of the paths the a block array can create
  }
}
Field level:

{
 name: {
  en
  de
  etc.
 }
  content: {
    en: {
       //lots of paths
    },
    de: {
       //lots of paths
   }
}

That’s much clearer now. Thank you
