   That is the right next step.
   
   A general "dimension lookup" capability is too broad to move straight into 
implementation, because batch lookup, streaming cache refresh, async key-value 
enrichment, and consistency/TTL semantics all lead to different runtime 
contracts.
   
   Please open the STIP first, and keep the first version narrow. The most 
important things to make explicit are:
   1. the concrete target scenario
   2. whether this is for batch, streaming, or both
   3. cache/refresh and staleness semantics
   4. failure and retry behavior
   5. whether the capability belongs in SQL, a new transform, or another layer
   
   Until that STIP exists, I would keep this issue as the umbrella feature 
request rather than starting implementation work directly.
