Under the hood, each “record” in Cosmos DB is a JSON document with an ID and partition key that, together, define its globally unique ID.

This is similar to the type of redirect used if you’ve registered multiple domains and you want to direct all of your traffic to your primary URL.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).
