ADVPERF04-BP05 Manage high volume user profile data

The user profile database is typically large, ranging from 100-200 million to 5 billion user profiles and contains a wide range of data about users' online activities and interactions. Hence this should be retained for a short time in the range of 30 days -1-year max, to manage data storage costs and data query latency SLO’s.

Implementation guidance

Use an in-memory database with a data cache strategy using Amazon MemoryDB.

Avoid replicating user profile data across multiple Regions due to high latency and data transfer costs. We recommend storing user profiles local to the user.

In the event of multi-Region architecture, implement synchronization between periodically (for example, once or twice a day) rather than in real-time, as users are unlikely to be in two locations at once. Advertisers also often use geotargeting, so a user's profile may only be accessed from the Region the user is located in for a particular ad campaign.
