KiokuDB::Role::Immutable - A role for objects that are never updated.


    with qw(KiokuDB::Role::Immutable);


This is a role for objects that are never updated after they are inserted to the database.

The object will be skipped entirely on all update/store operations unless it is being collapsed for the first time, and its child objects will not be updated unless they are found while collapsing another object.

This means that:

    my $immutable = $kiokudb->lookup($id);



will not work, you need to update the child directly:
