Changing the architecture of a good production environment is stupidity but why not try if performance is increased by 10x.
Being an Email Service provider our primary job is inboxing mails and another is the realtime analytics where billions of transactions need to be updated in realtime so that our customers can act on the next campaign.
So these realtime analytics use to get updated using SSDB which was impressively fast but for a few deadlock conditions, the data update was delayed.
Here we got an idea of changing our architecture by introducing Redis has our primary NoSQL which has given incredible stats as compare to SSDB.
In this talk, I will be discussing the transition from SSDB with Perl, MySql to Redis with golang, elastic search with the help of some numbers, how we made a scalable infrastructure for real-time analytics and reporting keeping Redis as the backbone for data operations where millions of emails are sent per hour.
