Module ord_neu 

Source
Expand description

Trace and batch implementations based on sorted ranges.

The types and type aliases in this module start with either

  • OrdVal: Collections whose data have the form (key, val) where key is ordered.
  • OrdKey: Collections whose data have the form key where key is ordered.

Although OrdVal is more general than OrdKey, the latter has a simpler representation and should consume fewer resources (computation and memory) when it applies.

Structs§

OrdKeyBatch

OrdKeyBuilder

OrdValBatch
An immutable collection of update tuples, from a contiguous interval of logical times.
OrdValBuilder
A builder for creating layers from unsorted update tuples.
