Another option is to use a cloudfront hosted pixel, and have a cloudwatch job to schedule processing of that data every X minutes. This gives you ultra fast edge response time on your tracker, instead of slow lambda + api gateway, but you have to back-process the data. This should also cost less if you have a lot of traffic.

Instead of Google sheets, throw it to bigquery. Or reprocess hourly/daily into parquet then scan with athena.

I can't POST with a pixel though, and I care about event logging.

For sure, Google Sheets is just a free, easy and temp stand-in for a real data store.
