Hard to say. Since I don't know their compression technique I cannot say under which circumstances it performs good or bad. My gut feeling is that if you split the original table in binary tables, replace the actual values with references to them and introduce the proper indices (hash table or otherwise) that will be a pretty good general solution, especially if some of these tables/indices can be kept in main memory.
