Apr 1, 2026April 2026: Build-system stabilization for scylladb/scylladb by reverting duplicate test entries in CMakeLists.txt to fix build errors caused by duplicate rolling_max_tracker_test and symmetric_key_test targets. This fix restores a clean CMake build and prevents test-target collisions, enabling CI to pass reliably. No new features released this month; focused on build hygiene and test integrity to maintain developer velocity.

Dec 1, 2025December 2025 monthly summary for scylladb/scylladb: Implemented a major snapshot lifecycle overhaul and introduced a Snapshot Writer abstraction, enabling centralized, reliable data and metadata writing across table and sstables components. This lays the groundwork for consistent backups, faster restores, and easier future enhancements. Expanded S3/object_storage endpoint capabilities and improved configurability: shuffled construction args for s3_client_wrapper to align with gs_client_wrapper, added an 'extended' endpoint name overload for s3 client creation, and refactored endpoint_config handling to pass endpoint_config directly. Strengthened testing and documentation coverage: reused S3 fixtures in tests, added named constants for endpoint names, and introduced tests for endpoint configuration updates. Improved performance and maintainability with API refinements (ranges usage in get_built_indexes), code cleanup (removing dangling s3::endpoint_config mentions), and broader cleanup tasks. Increased reliability and stability: fixed startup observer race in storage_manager for endpoint updates, added experimental_list_directory support, and performed cleanup such as removing redundant lister::rmdir and removing unused boolean classes.

Oct 1, 2025Month: 2025-10 performance and reliability focus across scylladb/scylladb. Core work this month centered on async API refactors, streaming and data-path optimizations, and Seastar modernization to boost throughput, reduce latency, and improve maintainability. Major bug fixes and reliability improvements were delivered alongside expanded test infrastructure and improved developer ergonomics. Major bugs fixed this month included resolving a race between readdir and stat in the lister, which improved directory listing reliability under concurrent workloads. Key features delivered: - Get built_indexes relocation to view_builder with coroutine-based handler, enabling cleaner lifecycle management and lower latency for index lookups. - Coroutineized error_injection and relabel_config API handlers to improve asynchronous throughput and simplify error handling paths. - API streaming support and indentation fixes, including switch to request content streaming for relevant handlers, improving throughput for large payloads and code readability. - API cleanup: Column_family API block reduced coupling by removing the system_keyspace reference, simplifying maintenance. - SSTable data path optimization: construct output_stream for data instantly, reducing overhead and latency in emission paths, complemented by transport adjustments to align with the latest API model and by memory_data_sink and directory_lister improvements (generator-based lister and put overload). - Seastar modernization: updated submodule and upgrade to Seastar API level 9 to enable new sinks, buffers and improved concurrency handling. Overall impact and accomplishments: - Substantial reduction in latency for high-throughput paths, better resource utilization through streaming and coroutines, and a more maintainable codebase with clearer async semantics. - Strengthened reliability through targeted bug fixes, improved test coverage, and cleaner API boundaries, enabling faster iteration and safer deployments. Technologies/skills demonstrated: - C++ coroutines and asynchronous programming patterns, Seastar API level 9, and modern memory data sinks. - Streaming IO, token-based parsing improvements, and generator-based directory listing. - Code refactoring for better modularity (view_builder integration) and API surface cleanup. - Test infrastructure enhancements and debugging discipline to improve maintainability and traceability.

Aug 1, 2025Highlights for 2025-08: Delivered substantial sharded<database> support across the Column Family API and map-reducers, enabling operations on the sharded database directly (covering set_server_column_family, for_tables_on_all_shards, set_tables_autocompaction, set_tables_tombstone_gc, and CF stats/histogram/rate APIs). Tightened API integration by capturing and routing the sharded<database> context through CF handlers and patching map_reduce callers to use the sharded<database>. Completed a major config and architecture refresh (SSTables Manager config refactor and db_config rename) to improve configurability, live-update capabilities for select options, and reduce coupling to db::config. Implemented critical bug fixes in storage and metrics paths (S3 chunked download metric calculation, storage_service drain handler). Published documentation updates for system.clients scheduling_group and consolidated code paths for load/metrics-load handling into column_family. Demonstrated strong async/coroutine skills, refactoring discipline, and architecture-focused contributions with clear business value.
