Data Freshness Check

Quickly determine if data is fresh enough to use.

Freshness Check Process

For each table to check:

1. Find the Timestamp Column

Look for columns that indicate when data was loaded or updated:

  • _loaded_at, _updated_at, _created_at (common ETL patterns)
  • updated_at, created_at, modified_at (application timestamps)
  • load_date, etl_timestamp, ingestion_time
  • date, event_date, transaction_date (business dates)
