Does Aurora DSQL scale to 0?
So if there is no load on the DB there is no cost? Also is there a cold start overheating when making a request to the DB in low load scenarios?

Aurora DSQL measures all request-based activity, such as query processing, reads, and writes, using a single normalized billing unit called Distributed Processing Unit (DPU). Storage is billed based on the total size of your database, measured in GB-month. Aurora DSQL ensures your data is available and strongly consistent across three Availability Zones in an AWS Region. You are only charged for one logical copy of your data.
If you aren't making any requests (running SQL), the only charge is for data stored in the cluster.
Also is there a cold start overheating when making a request to the DB in low load scenarios?
Most clusters will never experience cold starts. If you do zero requests for an extended period (multiple weeks), you may experience a cold start.
Based on the information provided in the sources, there is no specific mention of Aurora DSQL scaling to zero or having a zero-cost option during periods of no load. Aurora DSQL is described as a serverless, distributed SQL database with virtually unlimited scale, but the sources do not explicitly state that it scales to zero capacity or has zero cost during idle periods.
The ability to scale to zero and have no cost during periods of inactivity is mentioned for Amazon Aurora Serverless v2, which is a different product. Aurora Serverless v2 now supports scaling to 0 Aurora Capacity Units (ACUs) after a period of inactivity, allowing customers to save costs when the database is not in use.
Regarding cold start overhead, the sources do not provide specific information about this for Aurora DSQL. The information available focuses on Aurora DSQL's ability to scale quickly and adapt to workloads of any shape, but does not mention potential latency in low-load scenarios.
It's important to note that Aurora DSQL and Aurora Serverless v2 are distinct products with different features. While Aurora Serverless v2 has the capability to scale to zero, we cannot confirm the same for Aurora DSQL based on the given information.
As for the note about the question being submitted by a Twitch viewer during a livestream at re:Invent 2024, AWS does indeed host regular livestreams called "re:Post Live" where users can submit questions and engage with AWS experts. These events provide opportunities for users to ask about and discuss various AWS technologies and features.
