Use Elastic Search to store data values sent by IOT devices in a period of time

Question

Escenario:

• Many many devices
• Each devices sent values each few seconds
• Want to store the values sent

I can use mongo with time series collections (https://www.mongodb.com/docs/manual/core/timeseries-collections/), but this needs a big mongo database, as the objetive to store this values is only save an read, dont modify that values and use them like historic data, i have thought use Elastic Search, for example, take a VPS put Elastic on it with big disk space (dedicated mongo is expensive than this option).

Mongo vs Elastic in this scenario?

Answer 1

IMO, Elasticsearch seems to be a better choice due to below reason, I don't know if same is available in mongoDB.

1. As you have a timeseries data, you can easily rollover your indices using the index lifecycle management, that saves your cost as well, as after sometime(according to your use-case), you can move your data to cheaper storage or even delete them automatically.
2. You can also visualise your data stored in Elasticsearch using Kibana.
