I try to save a case class with field of Set type. Something like this:

case class MyObject(setOfString:Set[String])

When I get my MyObject from db, i have this error:

The future returned an exception of type: java.lang.ClassCastException, with message: scala.collection.immutable.$colon$colon cannot be cast to scala.collection.immutable.Set.

Mongo version:

"org.mongodb.scala"      %%  "mongo-scala-driver"     % "2.1.0"

Any idea how can i force Set type to mongo driver?

Or you can have a look at [ReactiveMongo](http://reactivemongo.org/releases/0.12/documentation/) – cchantep Aug 24 '17 at 11:34
ReactiveMongo does't have bulk write, it's important in my case. – mkUltra Aug 24 '17 at 12:39
ReactiveMongo has bulkInsert, BTW `bulkWrite` is a MongoShell operation, not a MongoDB command – cchantep Aug 24 '17 at 14:16
