I am looking for advice or different point of view.
Short story long. I am having an application(Wordpress) that runs with local DB, but needs to load data from remote DB (some of template elements). I can load remote data via script calls, but I was wondering if I can load the remote DB in my local DB as views or some type of slave instance of the DB. I will perform only READ requests. What is a good approach for the task?
With regards to the approach of just script requesting data from remote DB, I am concerned with the numerous remote DB requests to be performed upon page load and the latency it will cause. I will try to tackle this by catching the html by Varnish. However, I am googling for other ways. Any suggestions!?
