Oct 1, 2024Month: 2024-10 • Focus on reliability and data integrity in the op-analytics data pipeline. Delivered a targeted bug fix for the BigQuery metadata table write path by replacing the incorrect import and function (overwrite_table) with the correct function (overwrite_unpartitioned_table). This prevents potential data corruption and runtime errors, stabilizing downstream dashboards. Commit: d1f34cdae74818e22d16f8ee9a21a5f69489ae03.
