• Create Keyspace

create keyspace FluentdLoggers
   with strategy_options=[{replication_factor:1}]
   and placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy';

• Create Columnfamily

#example CF

use FluentdLoggers;

create column family EventLogger
   with comparator = UTF8Type
   and column_metadata = [{
       column_name : tag,
       validation_class: UTF8Type,
       index_name : tag_idx,
       index_type: KEYS},{
       column_name : time,
       validation_class : BytesType,
       index_name : time_idx,
       index_type: KEYS}
   ];

Fluent tag and event.time is key in Cassandra.

• Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet

• Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it

• Fork the project

• Start a feature/bugfix branch

• Commit and push until you are happy with your contribution

• Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.

• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
