I need to keep the data of some entities in a single CF but split in two rows for each entity. One row contains an overview information for the entity & another row contains detailed information about entity. I am wanting to keep both rows in single CF so they may be retrieved in a single query when required together.

Now the problem I am facing is that I want to cache only first type of rows(ie, the overview containing rows) & avoid second type rows(that contains large data) from getting into cache.

Is there a way I can manipulate such filtering of cache entering rows from a single CF?
