ala888 Posted December 14, 2014 Share Posted December 14, 2014 Hello, Im trying to implement a small liking feature on my site, and want it to resemble somewhat of facebook's. Obviously due to facebook's large data set, different posts must be partitioned across multiple databases/servers.I would like to hear what you guys think they do in order to keep an up-to-date # of likes? Are they actually recursively connection to all of those separate servers in order to fetch this data, or is this some clever server/client side caching with memcached+cookies?

justsomeguy Posted December 15, 2014 Share Posted December 15, 2014 I would imagine they use database server clusters in general to store their data. For likes they probably store the total number of likes and also each individual like. Link to comment Share on other sites More sharing options...
