Learn how to store Terraform state in Amazon S3 with DynamoDB locking to prevent concurrent writes, including setup commands, IAM policies, and recovery steps.
Learn how DynamoDB Global Tables handle concurrent writes using Last Writer Wins (LWW) and how to implement versioning to prevent data loss in multi-region deployments.
Recognize DynamoDB provisioned throughput throttling, compare CloudWatch metrics, detect hot partitions, and apply fixes matched to the root cause.
A step‑by‑step diagnostic guide to identify and resolve high latency, throttling, and hot‑partition problems in DynamoDB tables, whether running in Provisioned or On‑Demand capacity.
DynamoDB conditional writes with a version attribute prevent lost updates on single items without transactions. Learn the pattern, costs, and limits.
Learn how to move Terraform state to an Amazon S3 bucket with versioning and use a DynamoDB table for locking, enabling safe team collaboration.
Learn how to switch a DynamoDB table to On-Demand capacity, verify the change, monitor cost, and understand the trade‑offs of pay‑per‑request pricing.
DynamoDB transactions let you atomically update or read across tables, but they double capacity usage and add latency. This guide explains the mechanics, shows a Node.js example, and weighs the trade‑offs so you can decide when to use them.
When you need to update several items across tables in a single, all‑or‑nothing operation, DynamoDB transactions offer ACID guarantees. This post shows how to use TransactWriteItems, handle idempotency, watch costs, and avoid common pitfalls.
