Apr 1, 2025April 2025 monthly summary for all-of-us/workbench. Key features delivered: - Visits data integration and UI display: Introduced 'Visits' as a new domain within concept sets; updated database scripts to include visit-related data; adjusted UI logic to display visits sourced from cohorts. Result: improved visibility and analytics of participant visits. Commits: 94fb3773589bcab99deb273a9b54ea120d1f6bed. - BigQuery data processing robustness and cognitive datasets handling: Hardened data processing scripts for BigQuery tables; cast floors to INT64 in ds_activity_summary; conditionally insert ds_emorecog_metadata only if the emorecog table exists; refined handling of cognitive datasets with emorecog presence. Commits: 10c6523014f9a4b9e570b7b3f039198e8478703a; ca125699399d6e4d7c735087e67c1aa101295af8. Major bugs fixed: - Indexing/build script fixes and maintenance: Adjust execution order to run bq ls only when emorecog exists; routine indexing maintenance to ensure operational integrity in preproduction and production. Commits: f3cb50dff0295f73bb3c981f47298ba05d1ad911; f693e1d7b9855e61206598052710a61da9a2defa. Overall impact and accomplishments: - Improved data integrity and reliability of data pipelines; better cohort- and visits visibility; safer deployments across preprod and prod; enables faster time-to-insight and analytics. Technologies/skills demonstrated: - BigQuery SQL and data engineering, domain modeling (Visits), UI integration, and DevOps/release readiness.
