In this article, I will compare the latencies of three serverless databases DynamoDB, FaunaDB, Upstash (Redis) for a common web use case.
I created a sample news website and I am recording database related latency with each request to the website. Check the website and the source code.
I have inserted 7001 NY Times articles into each database. The articles are collected from New York Times Archive API(all articles of January 2021). I randomly scored each article. At each page request, I query top 10 articles under the World section from each database.
