Multi-region consistency in DynamoDB Global Tables 🚀☁️ #82
Oracle Database@AWS is now GA, and Kiro is out!
In the previous issue, AWS Lambda now supports formatted Kafka events 🚀☁️ #81, we looked into the new supported Kafka events on Lambda functions.
Amazon DynamoDB previewed Multi-Region Strong Consistency (MRSC) at AWS re:Invent 2024. And now, this is generally available (GA).
DynamoDB provides you with a global table capability, which creates replicas across regions and the common challenge was ensuring the replicas are consistent (or in sync across all replicas). With MSRC, you can now write to DynamoDB with the multi-region-consistency STRONG attribute, ensuring that the replicas are consistent.
Donnie Prakoso shares more on this front in the blog - Build the highest resilience apps with multi-Region strong consistency in Amazon DynamoDB global tables
⭐ Pick of the month
This month’s Pick is “SQS + SNS“.
Bharat Geleda’s blog on asyncmcp : MCP with async transport via AWS SNS+SQS dives into how the asynchronous transportation with SNS topics and SQS queues with a simple guide and tutorial.
Jones Zachariah Noel N (Author) shares why observability matters for Event-Driven Architectures, bringing in challenges of EDA with AWS services and how metrics, specifically from SQS and SNS with New Relic integrations, help.
If you are confused about when to use SQS or SNS, the blog should help to understand it better, maybe a combination of it!
