Expand description

The trait for handling requests to datanode.

Required Methods§

source

fn handle<'life0, 'async_trait>( &'life0 self, request: RegionRequest, ) -> Pin<Box<dyn Future<Output = Result<RegionResponse>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Handles DML, and DDL requests.
