What is the name of the architecture with separate reading and writing to the database?

Question

Database

In the open spaces of Habr, there was once an article about architecture with separate reading and writing.
The essence is something like this: Instead of changing the state (for example, in the database), we create change records and process them with all sorts of handlers.

For example: Warehouse management. Instead of changing the balance of a particular product X, we write an event written off / added so much to the database.

Tell me what is it called?
