/*
    When a derived Class extends MetadataAdder, then the Class's number and fixed length field's memory can be counted automatically.
    But if the Class has variable length field, then you should overwrite get_metadata_size and call update_metadata_size when the Class's memory changes.

    get_metadata_size is only the memory of the metadata object itself, not include child objects,
    for example, TabletMeta::get_metadata_size does not include the memory of TabletSchema.
    Note, the memory allocated by Doris Allocator is not included.

    There are some special situations that need to be noted:
    1. when the derived Class override copy constructor, you'd better update memory size(call update_metadata_size) if derived class's 
    memory changed in its copy constructor or you not call MetadataAdder's copy constructor.
    2. when the derived Class override operator=, you'd better update memory size(call update_metadata_size) if the derived Class has variable length field;

    Anyway, you should update mem size whenever derived Class's memory changes.
