Data is always sent to all replicas but is only guaranteed by consistency
level, and ordering into guaranteed if you’re using appropriate serial
consistency levels
e.g. if you insert into dc1 with LOCAL consistency levels and read from dc2,
dc2’s state is strictly undefined and there is no
data is always written to all replicas in the cluster.
here is good diagram how this happens in the multi-dc cluster:

regarding the second question - theoretically, yes, it's
Hello,
I have a question regarding multi Datacenter replication.
In a multi datacenter(dc-1, dc-2) if two records are written into dc-1 is
there a guarantee that these two records replicate to dc-2 in the same
order or is there a possibility that second insert replicate faster than
first insert?
