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.

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..

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.
