Struct TrieChunker 

Source 
pub struct TrieChunker<U: ColumnarUpdate> { /* private fields */ }
Expand description

A chunker that unwraps RecordedUpdates into bare UpdatesTyped for the merge batcher.

The intended behavior is to produce chunks whose size is within 1-2x LINK_TARGET. It ships large batches immediately, accumulates small batches, consolidates as they exceed 2xLINK_TARGET, and ships them unless they drop below 1xLINK_TARGET.

The flow is into (or around) self.stage, then consolidated blocks into self.ready, each of which is put in self.stage

Trait Implementations§
