Combine several messages from MQTT into one request to DataBase

Another way (instead of the join) is to write a function that stores into one object (with the topic as the key) then store the object in flow.

Do you mean store into an array at Flow level variable?

See this article in the cookbook for an example of how to join messages into one object.

Looking to this option but can't understand it completely. It seems that I have to add a function that will modify MQTT msg into a way it can be received by Join.
