Trait SchemaProvider 

pub trait SchemaProvider:
    Send
    + Sync
    + Debug {
    // Required method
    fn get_schema<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = Result<Schema, ArrowEncodingError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Provides Arrow schema for encoding.

Sinks can implement this trait to provide custom schema fetching logic.

Required Methods

fn get_schema<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Schema, ArrowEncodingError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Fetch the Arrow schema from the data store.

This is called during sink configuration build phase to fetch the schema once at startup, rather than at runtime.
