February 2025 summary for pagopa/pn-infra: Implemented Data Historization Query Enhancements to make the historization process idempotent and date-parameterizable. The default behavior now processes yesterday’s data when no date is provided. The query was refined to use an EXCEPT clause for more efficient data insertion into the cache table, improving performance and data accuracy. These changes reduce duplication risks, enhance reliability for nightly runs, and improve auditability of historization jobs.

January 2025: Delivered a set of capacity-building CDC data platform enhancements in pagopa/pn-infra, emphasizing performance, data quality, and unified access across JSON and Parquet sources. Key outcomes include improved view schemas for Athena via CDC View Column Ordering, a JSON cache layer with Glue integration and a robust partitioned GlueParquetTable, and a unified materialized view combining JSON and Parquet CDC data. Additionally, CDC Parsed Data Handling was refined to ensure accurate schemas and simpler storage paths. These changes enable faster CDC analytics, more reliable data loads, and scalable storage for processed CDC data; supported by automated cache refresh workflows and configuration tweaks for union-based outputs.
