Combining DynamoDB On‑Demand Mode with Auto‑Scaling to Handle Spiky Workloads
Learn how to pair DynamoDB’s on‑demand mode with Application Auto Scaling policies that react to throttling metrics, giving your spiky workloads automatic capacity adjustments without over‑provisioning.
When to Use DynamoDB Transactions: ACID in a NoSQL Store
Need all‑or‑nothing writes across DynamoDB tables? DynamoDB transactions let you atomically write up to 100 items, but double the WCU cost and hit limits. This guide shows how to decide, code a sample, and watch for pitfalls.
Lock Terraform State with DynamoDB to Block Concurrent Runs
Use an S3 backend with a DynamoDB lock table so Terraform automatically serializes concurrent plan and apply operations.
DynamoDB Global Tables: When Active-Active Replication Fits Your Workload
DynamoDB Global Tables replicate data across AWS regions with last-writer-wins conflict resolution. Learn capacity limits, consistency trade-offs, and how to verify replication status.
Optimizing DynamoDB Access Patterns with Global Secondary Indexes
Stop using Scan operations for non-primary key lookups. Learn how to implement Global Secondary Indexes (GSIs) in DynamoDB to enable efficient queries while managing projection costs and eventual consistency.
Optimizing DynamoDB Data Retrieval with Global Secondary Indexes
Learn how to query DynamoDB by attributes other than the primary key using Global Secondary Indexes (GSIs), including configuration examples and cost-optimization strategies.
Choosing Between DynamoDB On-Demand and Provisioned Capacity: A Practical Decision Framework
A practical framework for picking DynamoDB On‑Demand vs Provisioned capacity, with cost crossover math, scaling behavior, operational signals, a worked e‑commerce example, and a step‑by‑step switch checklist.
Preventing State Corruption: Implementing S3 and DynamoDB Remote Backends in Terraform
Stop risking state corruption. Learn how to move Terraform state to S3 and use DynamoDB to prevent concurrent modifications in team environments.
