Here at Netflix, we serve more than 30 million subscribers across over 40 countries. These users collectively generate billions of requests per day, most of which require metadata about our videos. Each call we receive can potentially cull through thousands of video metadata attributes. In order to minimize the latency at which this data can be accessed, we generally store most of it directly in RAM on the servers responsible for servicing live traffic.
