Composable Queries with Ecto
summary
Ecto queries become composable data pipelines: extract query construction from execution, use keyword and query‑expression syntaxes, compose named transformations (sources, transformations, syncs) and pipe queries through query pipeline stages. Builds a paginator, Scrivener, that returns page limit/offset entries and computes total counts by plucking out clauses (removing order/preload/select) so counts work even on complex queries; approach comes from real‑world apps and proves practical.
