π Elasticsearch vs MongoDB β Whatβs the Difference? π€
Both are powerful NoSQL databases, but they serve very different purposes:
π Elasticsearch
Built for search and analytics
Uses Lucene under the hood
Supports full-text search, autocomplete, filters, and ranking
Ideal for logs, monitoring tools, search bars, etc.
Near real-time performance, great for dashboards (e.g. Kibana)
Query language: DSL (Domain Specific Language)
π¦ MongoDB
A general-purpose document database
Stores flexible BSON documents
Great for CRUD operations, apps, and services
Strong aggregation framework
Used in web apps, mobile apps, CMS, and more
Query language: Rich query syntax (find, match, aggregate, etc.)
π§ Summary:
Use Elasticsearch when you need blazing-fast search and analytics.
Use MongoDB when you need a flexible, scalable backend for storing and retrieving structured data.
