Managing relationships in Elasticsearch can be challenging, but we have nested queries and parent-child relationships to work around it, and more.

Data modeling in is not as obvious as it is when dealing with relational databases. Unlike traditional relational databases that rely on data normalization and SQL joins, Elasticsearch requires alternative approaches for managing relationships.

p.title, p.content, c.text FROM posts p JOIN comments c ON p.post_id=c.post_id WHERE p.post_id=1; If you have multiple data sets that need to be joined for your application, then Rockset is more straightforward and scalable than Elasticsearch. It also simplifies operations as you do not need to remodel your data, manage updates, or reindex operations.
