In this meetup, Andrew Morgan, a Staff Engineer at MongoDB, will walk you through the thinking, architecture and design patterns used in building a Mobile Chat App on iOS using MongoDB Realm Sync. The Chat app is used as an example, but the principles can be applied to any mobile app where sync is required. Andrew will focus on the data architecture, both the schema and the partitioning strategy used and after this session, you will come away with the knowledge needed to design an efficient, performant, and robust data architecture for your own mobile app.
