There were a lot of simpler options that came to mind while reading through this, frankly.

But I imagine the writeup eschews myriad future concerns and does not entirely illustrate the pressure and stress of trying to solve such a high-scale problem.

Ultimately, going with a somewhat more complex solution that involves additional architecture but has been tried and tested by a 3rd party that you trust can sometimes be the more fitting end result. Assurance often weighs more than simplicity, I think.

While kittenhouse is, unfortunately, abandonware (even though you can still use it and it works), you can't say the same about e.g. async inserts in ClickHouse: it's a very simple and robust solution to tackle exactly the problem the PHP (and some other languages') backends often face when trying to use ClickHouse

Yes, had similar questions. Wouldn't tuning the settings for the buffer table have helped avoid the TOO_MANY_LINKS error?
