Hi,
You can write with CL=EACH_QUORUM and read with CL=LOCAL_QUORUM to get
strong consistency.
Kind regards,

even with CL=QUORUM,there is no guarantee to be sure to read the same

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

Dear All,
We have a cluster with one DC1:RF=3,another DC DC2:RF=1 only for
ETL,but we found that sometimes we can query records in DC1,while
not able not find the same record in DC2 with local_quorum.How it
happens?
Could anyone please advise?
looks we can only run repair to fix it.
Thanks,
