Often in program logic, multiple different steps need to be taken that
|
||
|
|
are independent of each other, but their total result is needed before
|
||
|
|
the next step can be taken. In synchonous code, the usual approach is
|
||
|
|
to do them sequentially.
|
||
|
|
|
||
|
|
An asynchronous or event-based program could do this, but if each step
|
||
|
|
involves some IO idle time, better overall performance can often be
|
||
|
|
gained by running the steps in parallel. A Async::MergePoint object
|
||
|
|
can then be used to wait for all of the steps to complete, before
|
||
|
|
passing the combined result of each step on to the next stage.
|

This module was originally part of the IO::Async distribution, but was
|
||
|
|
removed under the inspiration of Pedro Melo's Async::Hooks
|
||
|
|
distribution, because it doesn't itself contain anything IO-specific.
