Let's define what database sharding is, why we use it, and let's code an example using Java + Postgres database!

Could you please explain what steps should we take if we want to add new shard?

Thanks for the video. But this is poor's man sharding, right? I thought in the video you'd make use of some sharding feature of postgres, but you literally created 3 instances that don't even communicate with each other. I would just make it explicit next time, but also I don't believe anyone is willing to do that in prod. Regardless, good video!
