Trait Batch

pub trait Batch: BatchReader
where
    Self: Sized,
{
    type Merger: Merger<Self>;

    // Provided method
    fn begin_merge(
        &self,
        other: &Self,
        compaction_frontier: AntichainRef<'_, Self::Time>,
    ) -> Self::Merger { ... }
}

An immutable collection of updates.

Required Associated Types

type Merger: Merger<Self>

A type used to progressively merge batches.

Provided Methods

fn begin_merge( &self, other: &Self, compaction_frontier: AntichainRef<'_, Self::Time>, ) -> Self::Merger

Initiates the merging of consecutive batches.

The result of this method can be exercised to eventually produce the same result that a call to self.merge(other) would produce, but it can be done in a measured fashion. This can help to avoid latency spikes where a large merge needs to happen.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
