Is there a limit to the size of the string data of a predicate (scalar, string type)?

I need to store images as base64 encoded data.

<_:per> <name "jack" .
<_:per> <profile_image> "iVBORw0KGgoAAAANSUhEUgAAAPAAA..." .

  1. Is there a limit on the size of the string ?
  2. Though the profile_image is not searched for, would it affect performance of dgraph while storing and retrieving large strings ?

Nope, None that I’m aware of.
