Fool around with MySQL. Enjoys 2 tables, you to definitely as the items desk in addition to other are (uid-viewed_object) mapping. A join create solve your trouble. Touches work well into the longest go out, till your hit a level. Thus i do not think is actually a bad 1st step.

Explore Grow filters. Your condition in the course of time comes down to a-flat membership situation. Provide a collection of ids, find out if the section of various other put. An effective Bloom filter out was an effective probabilistic investigation construction and that solutions set subscription. He’s very smaller than average extremely efficient. However, ya, the probabilistic in the event, not true negatives cannot happen, however, untrue advantages is. Very that is a trade-off. Check out this based on how their made use of :
