Best way to store an object collection.

[jeteve]

Hi monks. Here is my quest:

I wish to store a collection of heterogeneous objects under a key name in order to make them persistent. I don't need to query them, I just need to be able to give the key and retrieve the collection. I also like to use a RDMS server as storage backend.

I had a look to *Session* ( like CGI::Session ) or *Cache* (like Cache::FileCache ) but theses storage are dedicated to store temporaly objects so they don't really fit my needs since object destiny is to expire within those storages.

I also had a look at data serializers like Data::Serializer, but it don't seem able to use a database as storage backend.

What would you do you wise monks to cope with that issue ?
Thx !

Have you met the magic data pixie?

Wooow, it rocks :)

Have a look at Comparison of different PERL caching modules (with sample code).

BerkeleyDB with Storable (Database, very fast) may be a good starting point for you.

perltie seems appropriate - although the documentation foucuses on tying hashes, scalars and array, don't let this fool you - tie is just as good at tying objects to database entries.

You may want to look at Tie::DBI. If you have a complex data structure associated with each key (a complex hash of hashes, or the like), you can use Storable, Data::Dumper, or YAML to serialize the data structure to text and store that.

For a more database-centric view of things, look at Class::DBI.

You could use memcached.

And how does that make the objects persistent?

Are you talking about storing in RAM or in a file?
