Every function is registered in two forms:
- Scalar (
t_*): pass pre-collected lists, returns a list - Aggregate/window (
ta_*): use withOVER()for row-by-row results
🏎️ Scalar t_* |
🧑💻 Aggregate ta_* |
|
|---|---|---|
| Performance | ⚡ Fast — one pass over the full series, O(N) | 🐢 Slower — recomputes per window frame, ~O(N × window) |
| Ergonomics | Requires list(col ORDER BY date) + unnest to rejoin rows |
Natural SQL — plugs into OVER (PARTITION BY … ORDER BY …) |
| Best for | Backtests, full-history feature generation, large datasets | Dashboards, ad-hoc queries, mixing indicators with row-level columns |
