Hi,
So, there's two things where you'll see the impact of "lots of datacenters"
On the query side, global quorum queries (and queries with cross-dc
probabilistic read repair) may touch more DCs and be slower, and
read-repairs during those queries get more expensive. Your geography
matters a ton f
Hi, Multiple DCs are required to maintain lower latencies for requests
across the globe. I agree that it's a lot of redundant copies of data.

RF=3, is within a center, you have 3 copies of data.
If you have 3 DCs, means 9 copies of data.
Think about space wasted, Network bandwidth wasted for number of copies.
BTW, Ours just 2 DCs for regional DR.
Thanks,

Reading and writing with local_quorum should not be a problem in terms of
performance if all data centers are healthy. But Quorum queries will take
hit due to network latency and that is expected and I believe you are aware
of that.

We are planning to go with 5 DCs with RF of 3 in each. All DCs will have
reads and writes. Most queries are done at LOCAL_QUORUM.
A very few Simple and CAS queries (<0.1%) will be done at QUORUM
consistency.
