Interact::Later - Delay some tasks for later by dumping their data to disk
Can be used, for example, when you receive lots of
POST requests that you don't want to proceed right now to save database load.
This module will fastly store the data content on disk (with Storable) without the need to use a database or a job queue. I believe as Perl is fast at writing files to disk, we can hope good results. This is an experiment...
use Interact::Later; my $delayer = Interact::Later->new( cache_path => 'path/to/cache', file_extension => '.dmp' ); $delayer->write_data_to_disk($data); # Later... # Do it until there are no more files... $delayer->get_oldest_file_in_cache(); # Finally $delayer->clean_cache;
TODO Telling the story of what happened at work and the situation with databases, job queues, etc. that got troubled by the large amount of POST requests.
A list of functions that can be exported. You can delete this section if you don't export anything, such as for a purely object-oriented module.
To instantiate a new
Interacter::Later delayer, simply pass a hashref containing a key-value couple containing the following:
Keep it simple, it don't require a
/ in the beginning nor the end, and you will be able to access it through
$ pwd /home/smonff/later/ my $delayer = Interact::Later->new( cache_path => 'path/to/cache', ... ); say $delayer->class_path; # /home/smonff/later/path/to/cache/ # Note it add a / in the end
Retrieve the oldest file in the cache.
Flush the cache.
Retrieve a specific file by ID
Writes the cache files to disk using
Storable. It also checks that the cache path exists and if not, it creates it.
Returns the UUID so this way, the caller could re-use it (by placing it in a queue for example).
