A vendor-neutral, declarative data quality engine. Quick Start Edit provero.yaml : Run: Features - 20 check types : not null, unique, unique combination, completeness, accepted values, range, regex, email validation, type, freshness, latency, row count, row count change, anomaly, custom sql, referential integrity, distribution, cardinality, drift, cross table count - 3 connectors : DuckDB (files + in-memory), PostgreSQL, Pandas/Polars DataFrame - SQL batch optimizer : compiles N checks into 1 query - Data contracts : schema validation, SLA enforcement, contract diff - Anomaly detection : Z-Score, MAD, IQR (stdlib only, no scipy needed) - HTML reports : provero run --report html - Webhook alerts : notify Slack, PagerDuty, or any HTTP endpoint on failure - Result store : SQLite with time-series metrics and provero history - Data profiling : provero profile --suggest auto-generates checks - Configurable severity : info, warning, critical, blocker per check - JSON Schema validation for provero.yaml - Statistical checks : distribution (mean/stddev bounds), cardinality (distinct count/ratio), drift (PSI vs a discrete baseline), cross table count (row-count parity/ratio between two tables) - Connection pooling and retry : per-source pool sizing, connect timeouts, and bounded retry-with-backoff for SQLAlchemy connectors - Observability : structured JSON audit log, OpenTelemetry spans, and Prometheus metrics on provero run , with ","default_branch":null,"files":null,"tree":[],"storefront":"/r/provero-org","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/provero-org/provero/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
