You are learning good preview.

Coffee Fits Bagel try a premier-level relationship app you to focuses on bringing higher-top quality fits thru the recommendation expertise. I have fun with Craigs list ElastiCache within our recommendation tube to help you select regional pages which have geohashing, store element vectors to possess towards the-request representative similarity data, and you will perform set intersections discover common household members ranging from applicant fits. Coffee Fits Bagel also employs Redis to other novel explore cases, such as for instance a failing-knowledgeable consideration queue process for the asynchronous employee processes, and you may storing each-user guidance inside arranged sets. Subscribe our very own greatest study researcher and you will CTO even as we walk your through the use cases and you will buildings and you may stress a means to get advantage of ElastiCache and you will Redis.
