Making a Hertzsprung-Russell diagram from Gaia DR2 data with Elasticsearch

Elasticsearch was one of the open source products on my list to try out, ever since I got rejected for a couple of assignments as a consultant last year. Apparently it’s a popular product. But why do you need a search engine in a Big Data architecture? This I explain in my new video where I load newly released data from ESA’s Gaia mission in Elasticsearch with Logstash and visualize it with Kibana.

I’ve also created an extra video wherein I explain how the code works.

You can get the code I’ve used at my Github page.
