Is you read SLO more sensitive than write S
Hello Laxmiant,
your application has to deal with eventually consistency if you are using
cassandra. Ensure to have
R + W > RF
And have the repairs runing periodically. This is the best way to be the
most cosistent and coherent

Hi Alex,
You are right, that will solve the problem. but unfortunately i won't be
able to meet my sla with write each quorum . I am using local quorum for
both read and write.
Any other way ?

Hi,
What I meant fromActive/standby model is that even though data is being
replicated (asynchronously) to standby DC , client will only access the
data from active DC (let's say using local_quorum).
you have "to switch" your clients without any issues since your writes are
replicated on all DC.
Hello,
What do you mean by active/standby model ? Cassandra is designed to be
active/active inter DC.
So you have "to switch" your clients without any issues since your writes
are replicated on all DC.
Unless you would mean by active/standby that the keyspace is not replicated
on the second DC ?
We have 2 dc in active/standby model. At any given point if we want to
switch to standby dc, how will we make sure that data is consistent with
active site? Note that repair runs at its scheduled time.
I am thinking of below approaches :
1.Before switching run the repair (although it assure cons
