Re: What does the hash key, global => 1, do in CHI

There's documentation in CHI::Driver::Memory

global [BOOL]
Use a standard global datastore. Multiple caches created with this set to true will see the same data. Before 0.21, this was the default behavior; now it must be specified explicitly (to avoid accidentally sharing the same datastore in unrelated code).

If this is set to false then datastore will be set to a new reference to a hash.

Hi Fletch, Thanks for the quick response. I used `$cache = CHI->new( driver => 'Memory', global => 1 );` as an example to show how 'global => 1' was being used. I am not instantiating the CHI class that way. Actually, I am using: `my $cache = CHI->new( driver => 'File', root_dir => '/path/to/my_cache_dir' );` The documentation does not show the use of 'global => 1' with that example. I was curious why and when it is necessary to use it.	[reply] [d/l] [select]

`global` is an argument specifically for the "Memory" (CHI::Driver::Memory) driver. If you're using a different driver then you'd consult the documentation for the custom options that particular implementer uses (i.e. CHI::Driver::File for the relevant options for that module). Edit: Just to expound on this, the docs for CHI show the common constructor options that are available irrespective() of the driver being used; anything specific to a given driver module would be documented with the driver module. () I'm not really familiar with CHI so conceivably there could be some options that are incompatible with some drivers but I'm not aware if that's actually the case; the documentation for the individual drivers would say for sure were that the case.
