Oct 1, 2025October 2025 performance summary for awslabs/LISA: Delivered two key features that strengthen release readiness and operational visibility. Dependabot Dependency Update Workflow Optimization consolidates dependency update PRs across npm, pip, and Docker ecosystems and targets the develop branch to enable testing before merging to main. Ingestion Job Status Tracking adds backend API endpoints, data models, and frontend components to list and paginate ingestion jobs, with database indexing improvements (GSI) to speed queries. These changes reduce PR churn, shorten validation cycles, and improve observability of ingestion workflows, contributing to faster, more reliable releases.
