Know the data is right before anyone relies on it.
Tests, freshness and anomaly checks that run with your pipelines and flag bad data before a dashboard, an app or an agent relies on it.
Checks next to the code
Checks run with the pipeline: row counts, uniqueness, freshness and the rules your business cares about.
Fail loudly
A failed check records a quality issue on the table, visible in lineage, run history and the console.
Visible to agents
Agents read the health of a table before they answer from it, so a stale number is flagged instead of repeated.
In code
@s.asset_check(asset=raw_orders)
def positive_order_amounts(
raw_orders: ir.Table,
warehouse: s.WarehouseResource,
) -> s.CheckResult:
invalid = int(warehouse.execute(
raw_orders.filter(raw_orders.amount <= 0).count()
))
return s.CheckResult(
passed=invalid == 0,
metadata={"invalid_order_count": invalid},
)Use it, install it, or build on it
Every block on the platform comes three ways. Most teams use all three.
Use it
See check results for every run in the console.
Install it
Apps from the marketplace ship with their own checks.
Build on it
Your agent adds checks next to each model, in the same pull request.
Replaces Monte Carlo and Hand-written alert queries.
