March 2025 performance summary for wellcomecollection/catalogue-pipeline: Delivered key features to increase determinism and observability of the catalogue ingestion workflow, fixed stability and correctness issues, and strengthened CI/CD and infrastructure. The catalogue-graph ingestor trigger is now parameterised by pipeline date for deterministic runs, with added monitoring across the ingestor trigger and loader outputs. Observability was extended with loader_monitor tests and a Terraform-based monitor Lambda, plus initial state machine step and CI involvement. The team addressed stability/quality issues in ingestor components, corrected policy naming, and performed pipeline hardening including renaming end index to record count and general formatting. A new script to deploy all ingestor Lambdas accelerates release cycles. Overall, these changes reduce failure modes, improve release confidence, and provide better operational insight for business decisions.
