SELECT species, ROUND(AVG(distance_km)) AS avg_km

WHERE season = 'fall' AND banded_year >= 2020
GROUP BY 1
ORDER BY avg_km DESC;

Northern pintails lead at 4,672 km on average — nearly 4× the homebody mallard. Blue-winged teal take second.

An Agent-First Architecture

Hypertenancy: an isolated compute instance for every person, dashboard, and agent. Run fast, highly concurrent queries without resource contention.

Every person, dashboard, and agent session gets its own isolated DuckDB instance — a Duckling — spun up in milliseconds.

Agents fan out — every session gets its own isolated duckling, so a fleet of parallel agents never slows your dashboards. Cold starts land under 100ms.

One user's heavy query saturates their duckling — and nobody else's. No noisy neighbors, no queues, no warehouse-wide slowdowns.

Size each instance to its job, Pulse through Giga. Backfill on a Mega instance, run dbt workloads on a Standard, let end users query a fleet of Pulses.
