Elasticsearch

What is it?

Elasticsearch is an open-source search and analytics engine built on Apache Lucene. It is designed to store, search, and analyze large datasets in near real time using a distributed, horizontally scalable architecture.

What does it do?

Elasticsearch indexes data and makes it searchable through a rich query DSL. It supports full-text search, filtering, aggregations, geospatial queries, and real-time analytics, while automatically handling sharding and replication.

Where is it used?

Elasticsearch is widely used in search-driven applications, log and event analytics, observability platforms, e-commerce search, recommendation systems, and enterprise systems that require fast data retrieval at scale.

When & why it emerged

Elasticsearch was released in 2010 to simplify full-text search and analytics on large datasets. It emerged to provide a scalable alternative to traditional search systems while supporting real-time insights and distributed workloads.

Why we use it at Internative

We use Elasticsearch to power advanced search, analytics, and observability use cases. Its performance and scalability allow us to build fast, data-intensive features such as search, filtering, and log analysis in modern platforms.
