Which database to choose for real-time data?

Question

NoSQL

Good afternoon.
Please tell me the database for storing real-time data.
Essence in the following:
There are data on several objects arriving by different protocols on the server, arrive each 2-3 seconds. After processing, they need to be saved somewhere to be displayed in monitoring applications for each of the objects. Reliability and long-term storage of data is not necessary, they lose their relevance with each new package for a specific object, the loss of one package is not critical.
Those. they need to be quickly stored and retrieved for processing.
I mainly worked with classic databases, maybe there is something more suitable, streaming or NoSql databases, please tell me.
