Then I generally worry about permissioning who can write to the cache, who can read from it and that sort of thing and as the database already handles all kinds of permissions for me, I default to database.

@Leo – Is CHI the modern version of Cache::* then? How did you come across it? Speaking of which, that brings another blogpost to mind.

@Anonymous – thanks. But I’m more interested in the reasons why you use those things. Why don’t you just store to a plain file with storable for example?

We have an analysis pipeline which calls out to multiple webservices to retrieve sample information, often multiple times.

Because the pipeline cannot work without the Filesystem (it all manipulating files in a run folder), we chose to create a cache folder inside the run folder on the FS, and then retrieve from there. To save there, the first thing we also do is spider out for all the information we are going to need, which has the added advantage of croaking early if any of the webservice information isn’t available.

We have found so far that this has been a viable setup.

Cheers

Andy
