Orleans.FSharp.EventSourcing
Declarative event sourcing for Orleans grains in F#.
What it does
Provides the eventSourcedGrain {} computation expression for defining event-sourced grains with pure apply and handle functions. Bridges to Orleans JournaledGrain for durable event storage and includes Marten configuration helpers.
Quick example
open Orleans.FSharp.EventSourcing
type State = { Balance: decimal }
type Event = Deposited of decimal | Withdrawn of decimal
type Command = Credit of decimal | Debit of decimal
let bankAccount = eventSourcedGrain {
defaultState { Balance = 0m }
apply (fun state event ->
match event with
| Deposited amount -> { state with Balance = state.Balance + amount }
| Withdrawn amount -> { state with Balance = state.Balance - amount })
handle (fun state cmd ->
match cmd with
| Credit amount -> [ Deposited amount ]
| Debit amount when state.Balance >= amount -> [ Withdrawn amount ]
| Debit _ -> [])
logConsistencyProvider "LogStorage"
}
