Microservices and document db's go brrrrrrr. Data duplication is completely fine as long as there is only one source of truth that can be updated, all copies must be read only. Then the copies should either regularly poll the source or the source should publish update events that the copies can consume to stay in sync. It's simple stuff but keeps your system way more available and fast than having multiple services talk to a shared db or worse, multiple services constantly fetching data through a proxy.
