setting consistency level

[Sagar Kohli <sa...@impetus.co.in>]

Hi,

Can we define consistency level in yaml file(or at the time of designing cassandra data modal), my question may sound stupid since m still in process of understanding Cassandra :)...

Thanks and regards

Consistency is set by the client for each read or write requests. You define the Replication Factor when creating the Keyspace, either in cassandra.yaml or as part of the create keyspace statement using the cassandra-cli. 

For background...
Check the docs if any for the high level client you are using
http://wiki.apache.org/cassandra/API
http://wiki.apache.org/cassandra/ArticlesAndPresentations

Hope that helps
Aaron

Sagar,

Consistency level defines how your reads and writes should work. You can 
defer it according to your needs, defines what are your expectations 
when you are reading/writing data. Hence, they are not static to 
Keyspace/CF metadata.

With regards,
Mayank
