Document Validation

You can set validation rules for collections for updates and inserts.

The validator object consists out of MongoDB-Query-Operators.

// validator object
{ $or:
      [
         { phone: { $type: "string" } },
         { email: { $regex: /@mongodb\.com$/ } },
         { status: { $in: [ "Unknown", "Incomplete" ] } }
      ]
   }

Additionally you can set the validation level and a validation action, which determine the behaviour of MongoDB in case the updates and inserts don't respect the validation rules.
