What can be used for high concurrency besides java?-clojure, go, and rust

Both Java locks and CAS have an astonishing overhead (locks call local systems to block threads and cause high overhead ).

The actor message queue has its own serious problems (using actor will greatly increase programming complexity ).

Therefore, distributed development compromises the optimal solution based on business characteristics.

In the case of concurrent writing with fewer reads and more: Clojure STM,Use multi-Version Control to change the space timeProvides memory transaction rollback similar to MVCC, which is simple and efficient to the extreme.

In the case of a large number of writes, the task mechanism abstracted by go/rust on CAs can also make CAS development quite simple.
