Hello, I have a doubt regarding multiple instances on the supertokens core running at the same time? I'm looking at the self-hosted version, and was wondering if I have 3 docker containers running the supertokens core and pointing to the same DB does this create an issue or can I have as many containers running as I need. This is for a High Availability simulations on my side. The full use case is for example putting all my core instances behind a load balancer so I don't have a single point of failure.

Each core is stateless and you can run as many as you like connected to the same db

You don't even need a load balance in frontend since our backend SDK queries them in a round robin. You just have to give the connection URI in the following format:

Copy code

core1address;core2address;core3address;

this means I could even have all cores behind a single DNS entry and provide that to the backend sdk, so that bringing up new container instances is transparent for my application?
