Frequently Asked Questions

How does Neptune Analytics pricing work?
Neptune Analytics bills for memory-optimized Neptune Capacity Units (m-NCUs). Running graphs bill at the full m-NCU hourly rate, paused graphs bill at 10% of that rate, and graph snapshot storage is billed separately per GB-month.
When should I use Standard vs I/O-Optimized for Neptune Database?
Standard has lower base compute and storage rates but charges separately for database I/O requests. I/O-Optimized increases the base rate and includes database I/O, which is often better for I/O-heavy or more predictable workloads.
What does average NCU usage mean for Neptune Serverless?
Neptune Serverless bills in Neptune Capacity Units (NCUs). Enter the average NCU usage sustained across billed hours in the month to estimate your serverless compute spend, then optionally add database storage, backup storage, and I/O.
