Hi Everyone, I have a CF which currently has a large composite key. Let's say it has 5 components, A,B,C,D,E.
I know I need to be able to query and find all rows where A,B,C equal a certain value. And I also need to query when A,B,C,D are a certain value. Traditionally what is the best approach for this? * Composite key? Is it possible to query on components of the composite key? * Duplicate the fields I want to query on and create a secondary index * Expand the data into supercolumns for horizontal traversal * Create lookup tables and suffer having to do reads before being able to write updates Thanks
