In this video I explain shortly what Elasticsearch is and what it does. And then I load data from ESA's Gaia Digital Release 2 in Elasticsearch and visualize it in Kibana. The end result is a Hertzsprung-Russell diagram where you can see the different types of stars in the dataset.

The Elasticsearch index mapping, the Logstash config file and the VEGA code are downloadable here. Also the commands to load the data.
