Seamless RDS to DynamoDB Migration: Unlocking Scalability With the Dual Write Strategy

DZone

Migrating from Amazon RDS to DynamoDB can be a significant challenge, especially when transitioning from a relational database like RDS (PostgreSQL, MySQL, etc.) to DynamoDB, a NoSQL, key-value store. One of the most effective strategies for migrating data incrementally is the Dual Write approach. This allows you to keep both databases in sync during the transition, minimizing downtime and reducing the risk of data inconsistency.

The Hidden Cost of Success: Understanding Non-Fatal Errors in Microservices

Abhishek Tiwari

A recent research from Washington University in St. Louis and Uber Technologies reveals a critical but often overlooked phenomenon in microservices architectures: non-fatal errors. While these errors don’t cause system failures, they introduce significant performance overhead that can impact user experience and operational costs. Study by Lee et. al explores how prevalent are non-fatal errors and what impact do they have on the exposed latency of top-level requests?

Generative Logic

O'Reilly

Alibabas latest model, QwQ-32B-Preview , has gained some impressive reviews for its reasoning abilities.
