Size is a float value, measured in points. Modify this value to change

Spacing is a float value, measured in pixels. Modify this value to change
the amount of spacing in between characters.

UseKerning controls the layout of the font. If this value is true, kerning information
will be used when placing characters.

Style controls the style of the font. Valid entries are "Regular", "Bold", "Italic",
and "Bold, Italic", and are case sensitive.

CharacterRegions control what letters are available in the font. Every
character from Start to End will be built and made available for drawing. The
default range is from 32, (ASCII space), to 126, ('~'), covering the basic Latin
character set. The characters are ordered according to the Unicode standard.

как узнать какой сервис на каких пользователей подписан
хранить эту связь в redisможно и в редис. по сути прийдется хранить только маски какой диапазон на какой сервер идут. и при скейлинге - обновлять.
Или на каждого пользователя создавать по очереди? Или это все одна очередь и каждое сообщение должно быть вычитано каждым инстансом сервиса_1 а затем отфильтровано?
