Threads were all the rage in the 1990s. People were using them for
everything. One language (Java) absorbed threading right into its core DNA
(where is the locking API? Oh, it’s attached to the base “Object” type
itself!).
People backed off a bit after that. Nowadays we see a revival of the
“coroutine” idea, where preemption only happens at explicit “await”
points. For non-CPU-intensive workloads, this is much easier to cope with.
... and asynchronous I/O for RDBMS (with no buffer > copies) and the
RDBMS managing large record cache.
This is why POSIX has the disk-oriented “aio” API, for the diehard DBMS
folks. Linux also added “io_uring”, for high performance but not disk-
specific I/O.
