I have a Spring application using Postgres as the datastore. I would like to use ElasticSearch instead. If someone has experience making a similar change, I would appreciate hearing the details. Can anyone describe the code changes that may be necessary. I assume it’s not as simple as adding the “spring-data-elasticsearch” library and extending ElasticsearchRepository to all of my repository classes. If there is an example out there, can someone please post here? Thanks.
