Jan 1, 2026

January 2026 focused on delivering distributed aggregation optimizations for the skywalking-banyandb repository. Implemented push-down of sum and count aggregations to data nodes to reduce data movement, added shard-aware deduplication to ensure accuracy across replicated or sharded deployments, and introduced a counting aggregation function to enhance distributed analytics. A refactor of the deduplication logic improved correctness and maintainability. These changes improve scalability, performance, and data integrity for analytics workloads across distributed deployments.
