Hi,
I am just curious to know when Cassandra doc says the atomicity and
isolation is guaranteed for a row.
Does it mean, two requests updating a row- "R1" at different replica will
be candidate for atomicity and isolation?
For instance , I have a setup where RF is 2
I have a client application wh
We would try migration for some small keyspaces (with data of serveral
gigabytes across a dc) first,
but ultimately migration for several large keyspaces with data size ranged
from 100G to 5T, some tables having >1T data, would be scheduled too.
As for StreamSets/Talend, personally I doubt if usin

Atomicity and isolation are only guaranteed within a replica. If you have
multiple concurrent requests across replicas last timestamp will win. You
can get better isolation using LWT which uses paxos under the hood.

ok got it. So, only using LWT txn the updates across nodes for a particular
row can be isolated, so basically paxos would ensure serializable isolation
Thanks,
