Under load, however, that brings three critical questions into focus: How much work do we admit? Cheap threads can still build an expensive queue. What belongs inside a lock? A sleeping lock holder still makes everyone else wait. Who stops abandoned ... Read more

The idea is simple and surprisingly powerful: if you start a few related tasks together, you should manage them together. They succeed or fail as a unit. This sounds obvious, but it’s ... Read more

Ideally, this scenario is unexpected. However, given its status as a preview API, such changes can occur, as was the case here. These changes lend considerable maturity to the API, and I am hopeful it will now stabilize without requiring further ... Read more
