The Reddit problem: Learning from mistakes
- antirez 17y agoI've mixed feelings about this mistake. Even if your error was not using consistent hashing, what's preventing you to modify the program in order to use two caching systems for a limited period (the time needed to rebuild the cache)? So you can use a better distribution strategy, and finally shut down the old cache and use the new.
- rkt 17y agoI think Reddit will be doing something like that. Jereny from Reddit responded to the thread and mentioned they might be moving to cassandra. Its however not a trivial task for a site with that kind of load and data to cutover :) http://www.royans.net/arch/reddit-learning-from-mistakes/comment-page-1/#comment-534 http://www.royans.net/arch/reddit-learning-from-mistakes/com...
