Hi,
When some popular object expires from memcached, all its customers try to retrieve the object from database simultaneously, and the database becomes overloaded. If this object is requested about 100 times in a minute, and if the process of receiving it from DB, processing and storing in cache takes about a minute, then the database receives 100 identical queries. Do you have this problem? How do you handle it? Thank you in advance, Olga.
