Your quorum writers are only guaranteed to be on half+1 nodes - there’s no
guarantee which nodes those will be. For strong consistency with multiple DCs,
You can either:
- write at quorum and read at quorum from any dc, or
- write each_quorum and read local_quorum from any dc, or
- write at loc

We have a cluster with one DC1:RF=3,another DC DC2:RF=1,DC2 only for ETL,b
If you're writing into DC1 with CL = LOCAL_xxx, there is no guarantee to be
sure to read the same data in DC2. Only repair will help you
