I have a cluster in AWS Singapore region (SG), but I have Apps (Lambdas) running in SG as well as in the Hongkong (HK) region. In order to lower the read latency for HK, I’m planning to utilise Atlas multi cloud deployment to deploy a read-only cluster in HK.
after the changes, I noticed that the latency for HK App remain the same. I expect it to drop as I expect HK App would connect to the HK readonly cluster automatically because it’s the nearest, but apparently not.
I’m using the same connection uri before and after the deployment, i.e.,
where did it go wrong?
one way to try is to add some replica set tags, like so:
