LiveSourceHandle

laminar_sql::datafusion::live_source

Struct LiveSourceHandle 

Source 
pub struct LiveSourceHandle { /* private fields */ }
Expand description

Handle for swapping batches into a LiveSourceProvider.

Implementations§

Source§

impl LiveSourceHandle

Source

pub fn swap(&self, batches: Vec<RecordBatch>)

Replace current batches. In-flight readers that captured the prior snapshot continue to see the prior data; the next scan picks up the new one.

Source

pub fn clear(&self)

Clear all pending batches.
