Let`s say I would like to override default connection pool size from 100 to 10.

I will have following piece of code:

`

val clientSettings = MongoClientSettings.builder()  .applyToConnectionPoolSettings{
    ConnectionPoolSettings.builder().maxSize(10).build()  }
  .applyConnectionString(ConnectionString(mongoProperties.uri))
  .build()
return MongoClients.create(clientSettings)

`

It should set the max size to 10 but instead of I get 100(default value), this value is populated when applyConnectionString is applied to the MongoClientSettings.

Basically it overrides the values that I provided as I understand.

As a workaround I can set: maxPoolSize value to the : mongoProperties.uri and use it without applyToConnectionPoolSettings.
