● Music is the best way to express how one feels.● Well, Mysql has a soul too, it has a mood :)● Mysql can sing through each query(good/bad) it gets.● Every query, Mysql gets, is intercepted in log.cc and sent acrross to an MQ Server. Subscribers to the queue ,on receiving a message play a musical note depending on the query they get.
The symphony orchestra Subscribers to a Message Queue, who on receiving a message/query play a musical note S S S MQ DB Queries
Use case:Divide & Conquer General query log● Alternative to enabling general query log, which grows very fast in size and disk space becomes a concern on the master database.● The queries are sent out to a queue on an MQ Server and an army of subscribers who listen to the queue , log the query on receiving a message. ● The general query log can now be distributed (among the subscribers). ● More number of subscribers => smaller the log & easy to rotate.
