DESCRIPTION

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

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.

CONFIGURATION
