# ElasticSearch

> Send indexed log data to an ElasticSearch destination, with options for authentication strategy, compression, endpoints, and indices.

## Description

Typically you would use ElasticSearch to store and analyze large amounts of data which are of different structures and formats. An ElasticSearch cluster is composed of **Clusters**, **Indices**, **Nodes**, and **Shards** that help organize and manage how your data is stored. The data can then be efficiently and powerfully searched and analyzed.

ElasticSearch is usually used as a Pipeline destination when your log data needs to be indexed for searching. By setting up a Pipeline for your ElasticSearch data, you can use Pipeline Processors like [Dedupe](/telemetry-pipelines/dedupe-processor) and [Remove Fields](/telemetry-pipelines/drop-fields-processor) to clean data or drop it if it’s not valuable before sending it to ElasticSearch.
