Fucking elastic appsearch, too many requests per seconds and it dies. It doesn't go slow first, it just dies. No warning just a timeout that lasts until a manual restart in elastic cloud console. Besides being apparently the shittiest product in the elastic stack, it's also the worst documented. And yes I just scaled it up but not being able to handle indexing 100 documents per second with 8 vcpu and 8 gb memory is a shame.
