# Indexing
## Introduction
The `indexing` module is a module dedicated to indexing data from
enrichment (or possible directly from parsers) into various data stores
including Elasticsearch, Solr and HDFS.
## Deployment Options
There is currently one option for running indexing in Metron, which is as a Storm topology.
## Submodules
* metron-indexing-common - this module contains common indexing code including IndexDao related-classes.
* metron-indexing-storm - this module is home to Storm-specific code such as Flux files and Storm indexing integration tests.
