    # Product.none.sum(:price)

    # (default: false)
    #broken_alias_handling: true
    # (Deprecated) Maintain broken `and' method behavior that existed in Mongoid 7.3
    # and earlier for backwards compatibility: in some situations, conditions
    # already present in a Criteria object would be replaced by newer
    # conditions when `and' method is used instead of the new conditions
    # being added to the existing conditions. This would happen when using
    # the same operator on the same field multiple times. For example:
    #
    # Band.where(id: 1).and({year: {'$in' => [2020]}}, {year: {'$in' => [2021]}}).where(id: 2)
    #

    # options:  {}

    # embedded: false>

    # This is obviously incorrect as the {"$in"=>[2021]} clause is lost.
    # Notice that the clause is only lost when both clauses are added using
    # the #and method.
    # (default: false)
    #broken_and: true
    # (Deprecated) When exiting a nested `with_scope' block, set the current scope to
    # nil instead of the parent scope for backwards compatibility.
    # (default: false)
    #broken_scoping: true
    # (Deprecated) Maintain broken update behavior in some cases for backwards
    # compatibility.
    #
    # In Mongoid 7.3 and earlier, when assigning a value to an embedded
    # document, then setting it to nil, then assigning the original value
    # to it again, the second update would not work and the value for the
    # embedded document would remain nil. Take this case:
    #
    # canvas.palette = palette
    # canvas.palette = nil
    # canvas.palette = palette
    #
    # ... where canvas embeds_one palette.
    #
    # In Mongoid 7.3 and earlier, canvas.palette would be nil when we would
    # expect it to be palette. Set this option to true to keep this behavior,
    # set the option to false to perform the second update correctly.
    # (default: false)
    #broken_updates: true
    # (Deprecated) Time objects in Ruby have nanosecond precision, whereas MongoDB server
    # can only store times with millisecond precision. Set this option to
    # true to truncate times to millisecond precision when performing
    # queries on already loaded embedded associations (this is also called
    # "embedded matching" and is done completely in Ruby), to obtain the
    # same query results when performing time comparisons regardless of
    # which documents are being queried. Setting this option to false will
    # produce different results for queries on embedded associations that
    # are already loaded into memory vs queries on unloaded associations and
    # top-level models. (default: true)
    #compare_time_by_ms: false

    # Whether to join nested persistence contexts for atomic operations
    # to parent contexts by default. (default: false)
    join_contexts: false
    # (Deprecated) When this flag is true, the attributes method on a document will return
    # a BSON::Document when that document is retrieved from the database, and
    # a Hash otherwise. When this flag is false, the attributes method will
    # always return a Hash. (default: false)
    #legacy_attributes: true
    # (Deprecated) Maintain legacy behavior of pluck and distinct, which does not demongoize
    # values on returning them. Setting this option to false will cause
    # pluck and distinct to return demongoized values. Setting this option to
    # false will also allow retrieving *_translations fields from pluck and
    # distinct and will return embedded values themselves (i.e. without
    # putting them in a hash).
    # (default: false)
    #legacy_pluck_distinct: true
    # 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 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.
    # (default: false)
    #legacy_readonly: true
    # (Deprecated) Maintain legacy behavior of === on Mongoid document classes, which
    # returns true in a number of cases where Ruby's === implementation would
    # return false. Note that the behavior of === on Mongoid document
    # instances differs from both the behavior of === on document classes
    # and from Ruby's behavior of === on simple object instances regardless
    # of the value of this option.
    # (default: false)
    #legacy_triple_equals: true
    # Set the Mongoid and Ruby driver log levels when Mongoid is not using
    # Ruby on Rails logger instance. (default: :info)

    # as a BSON::Decimal128 instead of a string. (default: true)
    #map_big_decimal_to_decimal128: true
    # (Deprecated) Force ``BSON::ObjectId#as_json`` method to return the hash
    # { "$oid" => id.to_s }. When this option is false, and bson-ruby 5
    # is used, the return value will be the hexadecimal ObjectId string only.
    # (default: false)
    #object_id_as_json_oid: true
    # (Deprecated) When chaining the same operators that use the same field, setting this
    # feature flag to false will cause those operators to be combined using an
    # and. Setting this feature flag to true will cause the later chained
    # operators to overwrite the earlier ones. (default: false)
    #overwrite_chained_operators: false
    # Preload all models in development, needed when models use
    # inheritance. (default: false)

    # (Deprecated) Use ActiveSupport's time zone in time operations instead of

    # Return stored times as UTC. See the time zone section below for
