So, Microsoft decided that they were deprecating Transactional Replication with Updatable subscriptions. In that case, you have 2 options (if I am correct): Pay for Enterprise (if you are already not) and use peer-to-peer or use bidirectional transactional replication which is basically setting up a transactional from db1 to db2 and also transactional from db2 to db1.

The issue I see in both cases is conflict resolution. With updatable subscriptions, you could specify how to handle the conflict. With either of these 2 options (from what I can tell) you cannot allow the engine to handle this for you. You must do it manually.

Any thoughts? Seems like a slap in the face to those who have been using MS for years and a damn good reason for companies that rely on updatable subscriptions to not upgrade to 2012.

Thanks,

For those interested... It seems that they did not "deprecate" the feature of Transactional Replication with Updatable Subscriptions, but removed the option from the Wizard. You can still create a publication through sp_addpublication and then add the subscription (with the same settings) either through the wizard or manually. Seems kind of silly to me.

Thanks,

Does anyone know if the feature is mentioned my MS as deprecated, or was this just noticed by some in the Wizard? I cannot find any actual MS documentation on the feature being deprecated.

Well... As a final update I have found that it will in fact be removed later on an MS site.

That link shows a number of features of updatable subs that are removed - while this says the entire feature (itself) is being deprecated:

Hi,
Have you researched your go-to for replacing this feature? I did not know that bi-directional needed a custom conflict resolution, but did with p2p. I had a question posed today about a topology requiring a 'local' server in London, and another set of servers in the US, their thinking was that they wanted to update only a local server. In that case P2P would work, but I can't guarantee only 'limited' DML.

Any other things that you've uncovered that you can share? Sort of a tough nut to crack; Oracle has some good arguments for their built-in methods to handle this. Seems that we have to do a 'hack' in order to match their features (ie mirroring combined with clustering, hag, etc).

Thanks
Lee
