Preview aggregate stats for a recipe (without materializing)

Runs aggregate-only queries via ds.omop.table.stats to show safe row and person counts for the tables referenced by the recipe's variables. This provides a quick sanity check without materializing any server-side datasets.

Usage

recipe_preview_stats(
  recipe,
  scope = c("per_site", "pooled", "both"),
  symbol = "omop",
  conns = NULL
)

Arguments

recipe

An omop_recipe object.

scope

Character; "per_site", "pooled", or "both".

symbol

Character; OMOP session symbol on the server (default "omop").

conns

DSI connections or NULL (uses active connections).

Value

A dsomop_result with aggregate stats per table.
