Amazon DocumentDB is a nice product when used for smaller registers about websites or when tabular information is needed. However, when you need more volume or more registers, it becomes complicated because the performance adjustments and tuning are challenging. It's very complicated because there aren't many parameters to adjust, and query optimization is difficult due to limited options. You only have methods and index creation available. Many customers tell me, 'I don't have another way. I need to change the instance type or add another node.'
