Dec 1, 2024December 2024: Delivered reliability and resource-efficiency improvements for SolaceIO.Read in Shopify/discovery-apache-beam. Consolidated initialization and finalization of checkpoints, ensured finalizeCheckpoint always executes to prevent unacknowledged messages, wrapped acknowledgments in resilient error handling, and stored messages in a checkpoint-referenced queue. Introduced a SessionService cache with eviction and idle-cleanup to optimize runtime resources. Included rollback of prior changes that destabilized behavior to restore baseline reliability. These changes improve end-to-end delivery guarantees, reduce failure modes in streaming reads, and enhance stability for downstream consumers.
