[jira] [Commented] (CASSANDRA-7076) Simplify CQL create keyspace syntax

["Matt Stump (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-7076?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13978435#comment-13978435 ] 

Matt Stump commented on CASSANDRA-7076:
---------------------------------------

The problem is that the pendulum has swung the other way. Users are deploying with a misconfigured replication strategy resulting poor user experience for both availability and performance. Often these misconfigured clusters are then compared to other database technologies (Mongo, Couch etc..), and C* will be ruled out by this initial experience.

> In order to simplify the new user experience we should make the specification of the replication strategy when creating a new keyspace optional. Additionally the NetworkTopologyStrategy should be made the default with a RF of 1 per existing datacenter.
> This proposal would make the two operations equivalent:
> {code}
> CREATE KEYSPACE test WITH replication = {
>   'class': 'NetworkTopologyStrategy',
>   'ExistingDC': '1'
> };
> {code}
> {code}
> CREATE KEYSPACE test;
> {code}
