Every time the browser makes a cross-origin request, it first makes a preflight request to make sure it can actually send the request.
Since API Gateway charges per request, you’re billed for both the preflight and the main request.
Stop wasting money on CORS preflight requests.
Here's a quick tip for reducing API Gateway costs. 👇
I’m pleased to share that I’m starting a new role at Kraken as a senior software engineer, promoting the adoption of clean energy.
If you’re not familiar with Kraken or its 60 million customers, check out this Financial Times article from yesterday.

How do you retain autonomy, empower teams and provide consistency in over 300 paths to production in under 6 months for IPO?
A great story from Pia Nilsson on how the platform at Spotify created Backstage.
Thank you @pete-naylor.bsky.social for your sharing your thoughts. My primary experience with AWS DB services has been with DynamoDB so far so I appreciate the insight, particularly into hot key contention as that is not something I have really considered before. One for the future!
@leeroyhannigan.bsky.social thanks for the context mate. Unfortunately I can’t amend my initial post to add this additional information 😬 but appreciate you responding.
If you are using #AWS or just interested in solid technical advice, you should listen to the Heroes: bsky.app/profile/did:... #listentotheheroes
@werner.social It’s fantastic the recognition you are giving to those who tirelessly support and inspire the AWS community. Whenever I’m scratching my head on a problem, 9 times out of 10 I’ll end up using a solution from an #AWS hero. #listentotheheroes
A week late however .. Terraform v1.10 now supports ephemeral values 🎉🎉
This is going to simplify workflows massively. #terraform #hashicorp #iac

..but the pattern was a relic of its time pre on-demand / auto-scaling etc.
What I’m trying to figure out now is when you’d use DynamoDb over the new Aurora DSQL? #AWS #DynamoDb #AuroraDSQL #re:Invent

As a follow up to the post I made yesterday re:DynamoDb concurrent updates..
There is an excellent post from last year written by @pete-naylor.bsky.social discussing why you probably don’t want to implement such a single table pattern as it not only locks you into configuration inflexibility..
Updates with conflicting attributes however, it’s likely better to have a single service aggregating the writes of the artefacts and using versioning/optimistic locking so that writes can be rejected if obsolete.

This nullifies any issues with the order in which update was received as you are not going to conflict on attributes. An example could be multiple microservices that make up a larger bounded context writing their own specific artefact i.e a product price , inventory to a record.
An interesting characteristic of DynamoDb that I learnt recently is that due to its internal “Leader model”, concurrent updates to the same record do not cause any concurrency issues as long as each update modifies a different attribute on the record.
Throughly enjoyed @quinnypig.com’s re:Invent roundup this morning. His sarcastic perspective on very valid issues in the AWS eco-system resonated with my northern British pessimism on a gloomy/stormy day.

All I could find in the docs is:
“Zero-ETL integration does not support transformations while replicating the data from transactional data stores to Amazon Redshift. Data is replicated as-is from the source data base. However, you can apply transformations on the replicated data in Amazon Redshift.”
