You should check how Erlang / Elixir database drivers handle that.

In my experience with Elixir there are never many processes that have a state to save in a database. Eventually it's the same load no matter if the implementation is actor based or object oriented.

but then how do you deal with transactionnal behaviors ?

Check Elixir's Ecto module https://hexdocs.pm/ecto/Ecto.html

The general idea is to build the transaction in a pipeline of function calls. Each function gets the old definition of the transaction as an argument and returns a new one. Eventually the call at the end of the pipeline executes the statements in the definition, wrapping them in a transaction.

If the question is how to deal with 100 or 100 k concurrent transactions, the answer again is in the same way a cluster of servers running programs written in any other language do. Eventually SQL is SQL.
