Partitioned Tables

When profiling partitioned tables in BigQuery, OpenMetadata applies a default partition query duration of 1 day for time-based partitions. This conservative setting prevents excessive data scans but may result in no Sample Data or Column Profile Metrics if no data falls within the default window.

Resolution

You can adjust this behavior directly from the UI:

  1. Navigate to the table's detail page.
  2. Edit the profiler configuration.
  3. Update the partitionQueryDuration under Partition Config to a wider window (e.g., 30 days) as needed.

This change allows OpenMetadata to access a broader data range during profiling and sample data collection, resolving the issue for partitioned tables.
