问题 TL;DR; Is it possible to listen on changes through spring-webflux & spring reactive data ? End of TL;DR; Hi, I did few tutorials regarding new spring webflux module and spring mongo reactive.

问题 I'm trying to find an easy way to sync data in mongoDB 4.x, to elasticsearch 6.x . My use case is for partial text search that is supported by elasticsearch but no supported by mongodb. MongoDB is the primary database for my applications. All solutions i found seem outdated and only support older version of mongoDB / elasticsearch.

Thank you 回答1: Here are couple of ways of creating an instance of MongoClient ,

问题 I'm looking for an elegant solution for persisting localized data in MongoDB in my Spring application. In the example below there is a basic solution for persisting localized data for the field description . As already suggested in how-to-do-i18n-with-mongodb the schema for localized data is "description": [{ "locale": "es", "value": "someESvalue" }, { "locale": "en", "value": "someENvalue" }] Given that, the entity looks like this: @Document(collection = "foo") public class Foo implements
