I was finding the script too slow running on my local machine, because the SQL RTTs were too slow - and with one connection, they were essentially a serial bottleneck, not taking much advantage of our concurrency.
Here, I instead add a `--dump` option, which outputs SQL to stdout. I then uploaded the resulting SQL to the DTI box, and ran it up there. Doing the network part fast on my machine, and the SQL part fast on the cloud machine!
I first considered uploading this script to the cloud machine, but it's an old Ubuntu and I couldn't figure out how to install a recent NodeJS onto it 🙃
This reverts commit 0f7ab9d10e.
The Production Vercel deploys don't seem to like how I did this build trick, even though the Preview deploys seem fine with it 🤔 Reverting for now, sent a message to Vercel support.
Just gonna bulk load all those manifests into the db, and then that should make most loads notably faster by removing the net request! 🤞
We'll still load manifests inline sometimes, but only the first time anyone pulls up the layer in impress-2020. After that, it should be cached forever!
