Module lookup 

Lookup table types and predicate pushdown.

Lookup Table Module

Types and traits for lookup joins in streaming queries.

Lookup tables allow stream events to be enriched with data from external sources (databases, object stores, caches) at query time.

Module Overview

• predicate: Filter predicates for source pushdown
• table: LookupTable trait, LookupResult, strategy/config types
