Trait JoinWindowStore

A typed windowed store that retains duplicates.

Every put with the same (key, timestamp) builds a distinct composite key from an incrementing seqnum, so the duplicates coexist in the backend. The store keeps the values RAW, with no ValueAndTimestamp wrap. The stream-stream join processors use it.

Required Methods

fn put<'life0, 'async_trait>( &'life0 mut self, key: K, timestamp: i64, value: V, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

fn fetch<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 K, time_from: i64, time_to: i64, ) -> Pin<Box<dyn Future<Output = Vec<(i64, V)>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
