This was a project that I built to explore if we could build a cheaper elastic search alternative using a FaaS service model. I didn't use a DB. Just S3, Lambda and API Gateway. I even did a performance analysis for latency times. It was a fun experiment, just deploy from the Serverless Repo and everything will work out of the box.

This is an awesome idea. I love ElasticSearch and use it all the time but I can see using something like this for smaller projects where running an ES cluster makes no sense.

I haven't tried running but assuming the best... great work!

Thanks, there's still a lot of performance improvements to make.

But I don't understand, why are the run times so incredibly high? 15 seconds to looks through 18k records? Should be <10ms (ignoring network latency), or what am I missing?

I should have been more clear. That's indexing latency, so the time it takes for a document to appear after you add it.

Checkout the graph below. That should show the search query latency
