# Cache::Async ... A Concurrent and Asynchronous Cache for Perl 6. ## Features * Producer function that gets passed in on construction and that gets called by cache on misses * Calls producer async and returns promise to result, perfect for usage in an otherwise async or reactive system * Transparent support for producers that return promises themselves * Extra args can be passed through to producer easily * Locked internally so it can be used from multiple threads or a thread pool * Limits on cache size and optionally entry age * Propagates exceptions from producer transparently * Monitoring of hit rate ## Upcoming Features * Optimizations of the async producer case * Self-warming caches * Object lifetimes can be restricted by producer function ## Example usage my $cache = Cache::Async.new(max-size => 1000, producer => sub ($k) { ... }); say await $cache.get("key234"); ## Documentation Please see the POD in lib/Cache/Async.pm6 for usage scenarios and details on how to use Cache::Async. ## License Cache::Async is licensed under the [Artistic License 2.0](https://opensource.org/licenses/Artistic-2.0). ## Feedback and Contact Please let me know what you think: Robert Lemmen
