We have a multi-cd publishing situation I can use some help with.
We are in an Azure PAAS situation, with the CM and 1 CD server located in the US. We also have a CD Server and SQL database in China (using Azure China/21 Vianet). Due to the fault tolerance, we decided to use replication to move the data to China. So we setup a publishing target in the US called web_china and can publish to that database. We then use replication to copy the data from the US to China.
The issue is that the replication can take up 5 minutes and by that time the publish:end:remote event has already been processed by the China CD server. So even though the data is in the web_china database in China, due to caching (?) the changes are not visible. If we publish the item a second time (since it is already in China), it appears on the site.
I have tried to add a task that runs in China and clears the cache on a regular basis. It clears both the Html Cache, MVC Cache and Rendering Parameters Cache. However even after running, the item is not visible in China. I then tried to delete all Caches, but that brought the site to a grinding halt.
Is there another cache that I should clear to get the published changes to show up?
Or is the better idea to just convert to using Publishing Service, which is a much more fault tolerant process.
