    # Configure the File::Multi store with a catmandu.yml file
    $ cat catmandu.yml
    ---
    store:
      files1:
       package: File::Simple
       options:
          root: /data1/files
      files1:
       package: File::Simple
       options:
          root: /data1/files_copy
      multi:
       package: File::Multi
       options:
           stores:
               - files1
               - files2
    ...

    # List all the folder in the multi store as YAML
    $ catmandu export multi to YAML

    # Add a file to the multi store with ID 7890 and stored name data.dat
    $ catmandu stream /tmp/data.dat to multi --bag 7890 --id data.dat

    # Download a file from the multi store
    $ catmandu stream multi --bag 7890 --id data.dat

    # In Perl
    use Catmandu;

    my $store = Catmandu->store('File::Multi' , stores [
        Catmandu->store('Simple', root => '/data1/files') ,
        Catmandu->store('Simple', root => '/data1/files_copy') ,
    ]);

    my $index = $store->index;

    $store->index->each(sub {
        my $item = shift;
        printf "%s\n" , $item->{_id};
    });

    # Add a folder to the multi store
    my $item = $store->add({ _id => '1234');

    # Retrieve the folder bag
    my $files = $store->files(1234);

    # Listing of all files
    $files->each(sub {
        my $file = shift;

        my $name         = $file->_id;
        my $size         = $file->size;
        my $content_type = $file->content_type;
        my $created      = $file->created;
        my $modified     = $file->modified;

        $file->stream(IO::File->new(">/tmp/$name"), file);
    });

    # Add a new file
    $files->upload(IO::File->new("</tmp/data.dat"),"data.dat");

    # Retrieve a file
    my $file = $files->get('data.dat');

    # Stream the file to an IO::Handle
    $container->stream(IO::File->new(">/tmp/data.dat"),$file);

    # This will delete the folder and files
    $index->delete('1234');

DESCRIPTION

The Catmandu::Store::File::Multi is a combination of many Catmandu::FileStore-s as one access point. The Multi store inherits all the methods from Catmandu::FileStore.

By default, the Multi store tries to update records in all configured backend stores. Importing, exporting, delete and drop will be executed against all backend stores when possible.

METHODS

new(stores => [...])

Create a new Catmandu::Store::File::Multi. The stores configuration parameter contains an array of references to Catmandu::FileStore-s based on their name in a configuration file or instances.

Catmandu::FileStore
Catmandu::Droppable

The index Catmandu::Bag in this Catmandu::Store implements:

Catmandu::Bag
Catmandu::FileBag::Index
Catmandu::Droppable

The file Catmandu::Bag in this Catmandu::Store implements:
