Episode notes
DocumentDB Is Catching Up, Not Leading
- Amazon DocumentDB v8 is AWS playing catch-up with MongoDB while charging for compatibility rather than running upstream MongoDB.
- Performance claims sound nice but come with the caveat of a compatibility asterisk that compliance teams will scrutinize.
Rust In Lambda Is Useful But Not Magical
- AWS added Rust support to Lambda, which appeals to performance-focused developers but doesn't eliminate operational pitfalls.
- Corey Quinn warns that memory safety won't save you from misconfigured timeouts and runaway bills.
Plan For MWAA Serverless Limitations
- Treat MWAA Serverless as limited to AWS-first operators and expect to stitch in other compute and billing services for custom work.
- Plan for separate monitoring because Corey Quinn notes there's no rich web UI and you'll rely on CloudWatch logs.
