For my current serverless project I'm using Fauna which I think is a better option than Dynamo. You get relations, complex queries, etc. You also get authentication and authorization baked-in. I haven't done any serious tests but I'd say on average my reads to Fauna from Cloudflare workers are 30ms. Seems a lot compared to querying a local instance of Postgres but since Fauna is distributed you end up getting much better latency on average for your worldwide users compared to a single DB in us-east-1. Writes take longer (probably around 200-300ms on average) but considering these are replicated to all Fauna servers with ACID I'm ok with that. I wrote a little intro to Fauna's query language which is very powerful if anyone is interested: https://github.com/PierBover/getting-started-fauna-db-fql https://github.com/PierBover/getting-started-fauna-db-fql
