Mar 1, 2026March 2026 performance summary for hyperledger-labs/splice: Delivered end-to-end bulk-storage capabilities across the Scan App, Helm, and Pulumi, with improved reliability, data integrity, and observability. Key features delivered include Bulk Storage integration in the Scan App, Bulk-storage support in Helm & Pulumi configurations, adoption of LedgerIngestionService (RetryingService) for bulk storage, and exposure of zstd compression level as a scan config, complemented by a Grafana dashboard for bulk-storage metrics and checksum verification for uploads. Notable quality improvements include backfilling dashboard fixes, bulk storage pipeline fixes, CI robustness improvements (graceful handling of empty update segments and metadata storage), leak fixes, and enhanced HTTP handling. Overall impact: faster, more reliable bulk data processing, better operator visibility, and stronger data integrity, enabling scalable data workflows and safer deployments. Technologies demonstrated: bulk-storage workflows, S3 proxying, compression configuration, V2 encoding in bulk storage, and end-to-end monitoring with Grafana.
