mongo-scala-driver :how to add connection pool size in MOngoClient Settings

Question

i am new to mongo scala driver i am trying to add connection pool size when initiating a mongo instance i am doing it something like this

  val settings: MongoClientSettings = MongoClientSettings.builder()
    .applyToConnectionPoolSettings(ConnectionPoolSettings.Builder.maxSize(100))
    .applyToClusterSettings(b => b.hosts(List(new ServerAddress("localhost")).asJava).description("Local Server"))
    .build()

  val mongoClient: MongoClient = MongoClient(settings)

value maxSize is not a member of object com.mongodb.connection.ConnectionPoolSettings.Builder [error] .applyToConnectionPoolSettings(ConnectionPoolSettings.Builder.maxSize(100))

what is the right way to do this?

It is a small typo on your code

ConnectionPoolSettings.Builder.maxSize(100)

should be

ConnectionPoolSettings.builder().maxSize(100)

The code with the Block would look like this:

val settings: MongoClientSettings = MongoClientSettings.builder()
  .applyToConnectionPoolSettings((t: ConnectionPoolSettings.Builder) => t.applySettings(ConnectionPoolSettings.builder().maxSize(100).build()))
  .applyToClusterSettings(b => b.hosts(List(new ServerAddress("localhost")).asJava).description("Local Server"))
  .build()
