ruliontion Worldwide energy shortage shows up in surging coal, gas and oil prices

The high prices in europe add significant political leverage (on the Russian side) to the much critized Nord Stream 2 pipeline. [1]

It is saddening to see these carbon intense fossil fuels expanding in the world’s largest economies during times of rapid and visible global warming. How are we ever going to stay below 4 degree C?

ruliontion Partitioning GitHub’s relational databases to handle scale

Interesting insights and refreshing to see large scale providers still relying on „old-school“ tech!

What I did not fully grasp - isn’t Vitess it’s own database system built on top of a K/V store similar to e.g. CockroachDB? Here it sounds like they only use pieces of Vitess in front of regular MySQL primaries with sharding?

It’s also curious that they sharded based on domains. I assume at some point the QPS on specific domains (e.g. Gist) will be so high that partitioning no longer is effective?

edit:// Looks like Vitess is indeed a set of tools on top of MySQL that allow for these type of scaling operations. It is not re-implementation of MySQL using different underlying technologies.
