Achieving isolation with Sagas

[Sebastian]

Hi there, 

Just wanted to know how to achieve isolation using Sagas. Going down to a concrete scenario let's say about a long live transaction having an action for reserving seats. How do I ensure isolation of let's say 2 seats from other transactions and to set a time out for that reservation to expire as well. If any of you have some code sample would be great.

Regards,

Sebastian

The Microsoft CQRS Journey uses this very use case as an example on sagas:

You can almost literally translate e.g. Fig 3 into code. What's missing
in the timeout, but that's must the matter of an additional (delayed)
event, such as "ReseverationTimedOut".
