So I built an entire record keeper app that we've been running for the past few weeks, but it's getting sluggish as we move on. It's currently based on sharepoint lists because at some point I figured that was the best option we had. I originally ignored the teams/dataverse option because I thought we would be exceeding 2GB, but after importing 9000 records into the sharepoint lists it's only showing around 3MB.
