People switched to whatsapp because:
1. It was free unlike SMS
2. It was ubiquitously available like SMS (unlike BBM)
3. It was genuinely a good product.
This feels like Whatsapp (Meta) is rug pulling the users once everyone has moved to Whatsapp, almost analogous to what Uber did. Drive Taxis out of business with predatory pricing, and then increase the prices.
I could be wrong, but with Citus, for most use cases, you can only have one co-ordinator node which fans out requests. So theoretically, you still can run into bottle necks at some point if 1 coordinator node is not enough.
With proxies like pgdog, multigres, and eventually Neki, these can scale out horizontally, so you get true unlimited scale.
Semi related question - I have always wondered, how do you tackle OOM issues at the proxy layer, i.e. let's say a particular SQL query requires proxy to fan out the query to multiple shards, which return a pretty large dataset. I'm assuming you would need to load this dataset in the ram to perform certain operations. What happens if the resulting dataset causes the proxy pod to go OOM?
They sure do, but looking at recent events, you can make an educated guess on which country has more influence over the other. Part of it can be attributed to spying and knowing dark? secrets.
Is it actually refreshing? It's actually refreshing to see Stripe staying private for so long. That means, they have a sustainable business model, and can take on projects that might benefit users in the long term despite negative short term consequences instead of focus on growing at all cost for the most part.
Serious question, have you been part of an org that had to scale orders of magnitude very quickly?
Anyone who has been part of that journey knows how painful it really is. A lot of times the systems to fail at all levels, and you have to redesign it from the first principles.
