[jira] [Updated] (CASSANDRA-7877) Tunable consistency across cross datacenters LOCAL_QUORUM + 1

     [ https://issues.apache.org/jira/browse/CASSANDRA-7877?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hari Sekhon updated CASSANDRA-7877:
-----------------------------------
    Summary: Tunable consistency across cross datacenters LOCAL_QUORUM + 1  (was: Tunable cross datacenter replication)

>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7877
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Hari Sekhon
>            Priority: Minor
>
> Right now tunable consistency allows for things like local quorum and quorum across multiple datacenters.
> I propose something in between where you achieve local quorum + 1 node at other DC. This would make sure the data is written to the other datacenter for resilience purposes but be better performing that having to do a full QUORUM or ALL write level across multiple datacenters.
