HOWTO: avoid or­phaned REST in­vo­ca­tions due to lost re­spons­es (Un­pub­lished)

Your REST ser­vice is in­voked and left pend­ing. How can you roll­back?

So you have a REST ser­vice and it is be­ing called - good, your project is a suc­cess

Now sup­pose you want to roll­back in­vo­ca­tions where the re­sponse is lost, so the caller nev­er knew your ser­vice ac­tu­al­ly did some­thing. This is an "or­phaned" in­vo­ca­tion of your ser­vice, leav­ing you with some garbage trans­ac­tion data that you don't want. How can you deal with this?

We of­fer two so­lu­tions:

• The clas­si­cal, ACID way, or
• Our new­er vi­sion for REST

Either of these will make sure that or­phaned in­vo­ca­tions are cleaned up af­ter some time­out.

En­joy!
