Hydrators 

Hydrators enable Discovery to write content processing results to a search index, knowledge graph, or NoSQL database. Discovery supports a wide variety of hydrators for these different data storage technologies. Hydrators publish processed data to different repositories or indices that are accessed to respond to search queries, or for other intermediate staging purposes.
