I would avoid Storable simply because it depends on the Perl version and the perl configuration

That seals the decision...thank you.

As I said in the question, I've not used Storable. I didn't know it was version-dependent. As such, it's not suitable for my needs here.

ADDED:
The database is MariaDB, which has a perfectly capable set of JSON functions.
