521 | Simple RPC extension for AnyEvent::Fork |
|
|
522 | |
|
|
523 | This module implements a simple RPC protocol and backend for processes |
|
|
524 | created via L<AnyEvent::Fork>, allowing you to call a function in the |
|
|
525 | child process and receive its return values (up to 4GB serialised). |
|
|
526 | |
|
|
527 | It implements two different backends: a synchronous one that works like a |
|
|
528 | normal function call, and an asynchronous one that can run multiple jobs |
|
|
529 | concurrently in the child, using AnyEvent. |
|
|
530 | |
|
|
531 | It also implements an asynchronous event mechanism from the child to the |
|
|
532 | parent, that could be used for progress indications or other information. |

535 | Simple process pool manager on top of AnyEvent::Fork and AnyEvent::Fork::RPC. |
|
|
536 | |
|
|
537 | This module uses processes created via AnyEvent::Fork and the RPC |
|
|
538 | protocol implement in AnyEvent::Fork::RPC to create a load-balanced pool |
|
|
539 | of processes that handles jobs. |
|
|

|
|
541 | Understanding of AnyEvent::Fork is helpful but not critical to be able |
|
|
542 | to use this module, but a thorough understanding of AnyEvent::Fork::RPC |
|
|
543 | is, as it defines the actual API that needs to be implemented in the |
|
|
544 | children. |
