Thanks Eoin.

When I first heard about AWS launching Document DB I was excited, but sadly yes, the pricing is prohibitive for me. Starts at $400/mo for a 2 instance cluster I think. It's also not as "truly serverless" as Dynamo as it requires VPC and isn't pay per usage.

Split/canary testing sounds a good idea for mitigating risk of the switch over. I'll just need to come up with a good strategy of keeping both in sync once I get to that stage of the migration.
