Trait StorageFactory 

pub trait StorageFactory:
    Debug
    + Send
    + Sync
    + Serialize
    + Deserialize {
    // Required method
    fn build(&self, config: &StorageConfig) -> Result<Arc<dyn Storage>>;
}

Factory for creating Storage instances from configuration.

Implement this trait to provide custom storage backends. The factory pattern allows for lazy initialization of storage instances and enables users to inject custom storage implementations into catalogs.

Example

#[derive(Debug, Clone, serde::Serialize, serde::Deserialize)]
struct MyCustomStorageFactory {
    // custom configuration
}

#[typetag::serde]
impl StorageFactory for MyCustomStorageFactory {
    fn build(&self, config: &StorageConfig) -> Result<Arc<dyn Storage>> {
        // Create and return custom storage implementation
        todo!()
    }
}

Required Methods

fn build(&self, config: &StorageConfig) -> Result<Arc<dyn Storage>>

Build a new Storage instance from the given configuration.

Arguments

• config - The storage configuration containing scheme and properties

Returns

A Result containing an Arc<dyn Storage> on success, or an error if the storage could not be created.
