The timeout manager will use the in-memory timeout storage, which is NOT suitable for production use. For production use, you should use a SQL Server (e.g. a locally installed SQL Express) or another durable database.
If you want to configure the timeout manager for production use, you can use one the following examples to get started:
<timeout inputQueue=""rebus.timeout.input"" errorQueue=""rebus.timeout.error"" storageType=""SQL""
connectionString=""server=.;initial catalog=RebusTimeoutManager;integrated security=sspi""
tableName=""timeouts"" />
to use the 'timeouts' table in the RebusTimeoutManager database to store timeouts. If the specified table does not exist, the timeout manager will try to create it automatically.
You can also configure the timeout manager to store timeouts in MongoDB like this:
<timeout inputQueue=""rebus.timeout.input"" errorQueue=""rebus.timeout.error"" storageType=""mongodb""
connectionString=""mongodb://localhost/SomeDatabase""
tableName=""timeouts"" />
to use the 'timeouts' collection in the SomeDatabase database to store timeouts. Please don't use the collection to store anything besides Rebus' timeouts, because otherwise it might lead to unexpected behavior.",
