Wouldn't start from there

Harry Pierson: "So when I said 'simple scenarios' above, I meant 'scenarios that don't need transactions'. (I take it as a given that RESTifarians aren't hot for WS-AtomicTransaction.) ATOM Publishing is a simple scenario because the web resource authoring scenario doesn't need transactions to protect updates to multiple resources at a time. If it did, I don't believe the REST as CRUD approach they use would work."

Here's a counter-example that transactionally updates multiple resources. People really do get stuck on transactions as the be all and end all of business computing - thought for the day - value exchange != transaction.

I along with others been reading and following web/rest awareness growing in and around MSFT, and aside from disbelieving that some ostensibly intelligent people have only recently gotten it, I'm struggling to understand some of the posts. It must be very complicated stuff that they're trying to bring onto the web. Stuff like a "long running transaction updating multiple distributed stores". Why would you want to do that?

Update (26th May 07): David Ing was kind enough to respond in a comment: "I thought what I wrote would be understood to mean 'I wouldn't start from there', but in the back/forth with Harry (a long running transaction?), maybe that intent got lost?". Fair enough, I might have jumped the gun; yet it would be a concern if people come to discover the overnight success called REST, only to be disappointed to find it doesn't solve the wrong problems.

Hello Bill,

In the context of the top-level link to my blog, I'm not sure if you are implying that I'm in favour of 'long running transaction updating multiple distributed stores' over the web or not (I'm not, of course).

I thought what I wrote would be understood to mean 'I wouldn't start from there', but in the back/forth with Harry (a long running transaction?), maybe that intent got lost?

Anyway, been reading your blog for a long time and thanks for the link.

- David
