Architecture Corner

Show Notes

Architecture Corner Newsletter Podcast explores the practical side of working with AWS DynamoDB, moving beyond basic concepts to understand how developers actually interact with this NoSQL database service. In this episode we will cover: The three categories of DynamoDB API actions and when to use each approach Expression attribute names and values for building dynamic queries Key optional parameters that control read consistency, sorting behavior, and return values The five types of expressions used in DynamoDB operations and their specific applications Practical considerations around filtering, projections, and the cost implications of different query patterns Update expressions and condition-based writes for maintaining data integrity

Architecture Corner Newsletter Podcast AI coding budgets are getting torched, and 2026 is the year the bill finally came due. In this episode, we dig into how token consumption became a productivity metric (and why that backfired), and what the industry is doing about it now that the free-for-all is ending. We will cover: Why token usage became a proxy for developer productivity — and how Goodhart's Law caught up with it The provider-side shifts (usage windows, model restrictions, pricing model changes) that reshaped agentic coding through early 2026 What's really driving your AI bill: subscriptions vs. API, caching mechanics, and model/thinking-effort tradeoffs Practical tokenmining strategies — from scripting deterministic steps to tuning your harness and mixing models Where the industry goes next as cost-conscious AI development becomes the norm

Once you ship a public API, you've made a promise. Keeping it while still moving forward turns out to be harder than most teams expect. In this episode, we will cover: What qualifies as a backward-compatible change, and what doesn't Why does introducing a new API version cost more than just writing new code The real reason clients delay upgrades, and what you can do about it How to support multiple versions without duplicating your entire codebase The adapter pattern is a practical way to isolate version changes at the edges Know more here: https://medium.com/itnext/the-challenges-of-evolving-your-service-api-versioning-8008349a1154 Subscribe, for free, to the Architecture Corner Newsletter at https://architecturecorner.substack.com
