Overview
Note:
a += b
is not a thread-safe operation on
Concurrent::Array
. It reads array a
, then it creates new Concurrent::Array
which is concatenation of a
and b
, then it writes the concatenation to a
.
The read and write are independent operations they do not form a single atomic
operation therefore when two +=
operations are executed concurrently updates
may be lost. Use #concat
instead.
A thread-safe subclass of Array. This version locks against the object
itself for every method call, ensuring only one thread can be reading
or writing at a time. This includes iteration methods like #each
.
