This is a reactive part of simple "Movie App" that contains movie microservice. In this app user can leave reviews for movies.
Movie - full information about movie.
EsMovie - information about movie for Elasticsearch.
The service registry pattern is a key part of service discovery. The registry is a database containing the network locations of service instances. A service registry needs to be highly available and up-to-date. One of the most popular implementations of this pattern is Eureka Service Registry.
Reactive producer is implemented as a part of Reactor Kafka. The producer sends messages to the consumer from other microservice (see ReviewMicroservice). The main goal of this implementation is to simplify communication between microservices: if the movie is deleted, all reviews for this movie should be deleted too. Also reactive consumer is added for sync Elasticsearch with Postgresql.
