Streaming API - persistence

Use case: Account is created using Salesforce Apex. Need to send this account information to external vendors.


To do this I was planning to use Mule ESB which will subscribe to a topic "Account create". The question is what if topic subscriber (Mule ESB in this case) goes down?  Will Salesforce try to deliver the event again till it succeeds?

No. Streaming events are not persistent. If the client subscription expires, the client will not receive the events happenned in the past while it was not subscribed.
