June 2025 performance summary for samvera/hyrax and samvera/hyku focusing on business value, reliability, and scalable metadata/indexing workflows. - Core metadata inclusion and indexing overhaul with configurable options implemented across Hyrax forms and indexers. This enables flexible core_metadata and basic_metadata inclusion with a configurable, centralized indexing path; supports schema-flexible forms and improved indexer behavior. Implemented via a series of commits to adjust configuration scope, move core metadata include to the appropriate level, and deprecate schema-based form field include where appropriate. The work reduces unintended metadata exposure, speeds up indexing, and simplifies future schema evolution. - Robust Redis queue error handling introduced for indexing and deletion operations: dedicated error queue names, enhanced rescue blocks, and re-queuing of failed items. This significantly reduces lost work due to transient failures and improves overall pipeline reliability. - Gems cross-platform compatibility improvements for google-protobuf and grpc (Alpine/Linux support): leveraged prebuilt binaries and locked platform-specific builds to ensure smooth installations and avoids build-time failures across varied environments. - Reprocessor: single_batch mode added for batch processing in Hyku, refactoring processing logic to respect current_limit. Enables predictable, incremental data processing and better control of resource usage. - These changes collectively improve business value by increasing system reliability, reducing deployment friction, enabling flexible metadata workflows, and improving processing throughput and predictability across the Hyrax and Hyku pipelines.
