I am planning to build a user activity timeline. Users on our system generates different kind of activity. For example - Search some product, Calling our sales team, Marking favourite etc. Now I would like to generate timeline based on these activities. Timeline could be for all events, filtered on specific set of events, filtered on time interval, filtered on specific set of events between time intervals. Composite column keys looks like a viable solution.
Any other thoughts here? Regards Siddharth
