    # When this flag is false, callbacks for embedded documents will not be
    # called. This is the default in 9.0.
    #
    # Setting this flag to true restores the pre-9.0 behavior, where callbacks
    # for embedded documents are called. This may lead to stack overflow errors
    # if there are more than cicrca 1000 embedded documents in the root
    # document's dependencies graph.

    # When this flag is true, any attempt to change the _id of a persisted
    # document will raise an exception (`Errors::ImmutableAttribute`).
    # This is the default in 9.0. Setting this flag to false restores the
    # pre-9.0 behavior, where changing the _id of a persisted
    # document might be ignored, or it might work, depending on the situation.

    # Whether to join nested persistence contexts for atomic operations
    # to parent contexts by default.
    # join_contexts: false
    # When this flag is false (the default as of Mongoid 9.0), a document that
    # is created or loaded will remember the storage options that were active
    # when it was loaded, and will use those same options by default when
    # saving or reloading itself.
    #
    # When this flag is true you'll get pre-9.0 behavior, where a document will
    # not remember the storage options from when it was loaded/created, and
    # subsequent updates will need to explicitly set up those options each time.
    #
    # For example:
    #
    #    record = Model.with(collection: 'other_collection') { Model.first }
    #
    # This will try to load the first document from 'other_collection' and
    # instantiate it as a Model instance. Pre-9.0, the record object would
    # not remember that it came from 'other_collection', and attempts to
    # update it or reload it would fail unless you first remembered to
    # explicitly specify the collection every time.
    #
    # As of Mongoid 9.0, the record will remember that it came from
    # 'other_collection', and updates and reloads will automatically default
    # to that collection, for that record object.
    # legacy_persistence_context_behavior: false
    # When this flag is false, a document will become read-only only once the
    # #readonly! method is called, and an error will be raised on attempting
    # to save or update such documents, instead of just on delete. When this
    # flag is true, a document is only read-only if it has been projected
    # using #only or #without, and read-only documents will not be
    # deletable/destroyable, but they will be savable/updatable.
    # When this feature flag is turned on, the read-only state will be reset on
    # reload, but when it is turned off, it won't be.
    # legacy_readonly: false
    # The log level.
    #
    # It must be set prior to referencing clients or Mongo.logger,

    # configuration file is the log level given by this option honored.

    # preload_models: false
    # When this flag is true, callbacks for every embedded document will be
    # called only once, even if the embedded document is embedded in multiple
    # documents in the root document's dependencies graph.
    # This is the default in 9.0. Setting this flag to false restores the
    # pre-9.0 behavior, where callbacks are called for every occurrence of an
    # embedded document. The pre-9.0 behavior leads to a problem that for multi
    # level nested documents callbacks are called multiple times.
