    System properties:

    The following properties can be set (e.g. using JVM -D options).

    • reactivemongo.api.bson.bufferSizeBytes (integer; default: 96): Number of bytes used as initial size when allocating a new buffer.
    • reactivemongo.api.bson.document.strict (boolean; default: false): Flag to enable strict reading of document (filter duplicate fields, see BSONDocument.asStrict).
