Ask HN: What is the best choice for Real-Time analysis database in 2020?

Good day HN.

I know it's a question that has already been asked, where everyone has their own concepts.

Recently I developed an analytics API for a high demand website using InfluxDB and MongoDB, this was fine in the first months but at the moment the service is not sustainable.

I am currently exploring options like Apache Druid, but I wanted to have opinions, from me, the best community of internet specialists.

Thks.
