Aug 1, 2025August 2025 monthly summary for redpanda-data/redpanda: Delivered feature-driven work including topic name normalization for Iceberg/DLQ tables with configurable dot replacement, validation, and test coverage; adjusted DLQ table naming to avoid dots. Also progressed Cloud Topics Reconciler with L1 IO and metastore enhancements, staging directory, L1 reader, and object_size support, plus replicated metastore integration. No separate major bugs fixed this month; primary focus on reliability through tests and architecture. Key outcomes include improved naming hygiene, more scalable data paths, and a foundation for faster ingestion and metadata management.

May 1, 2025May 2025: Delivered substantial modernization of the storage test suite and configuration for compaction lag. Migrated storage tests from Boost.Test to GoogleTest across multiple suites, with extraction of batch generators and utilities. Implemented min.compaction.lag.ms and its handling. Fixed performance/behavior issue by removing contiguous allocations in lock_manager (CORE-10056). Improved test reliability, maintainability, and performance visibility. This work enabled faster CI feedback and more predictable storage performance tuning.
