Aug 1, 2025August 2025 monthly summary for apache/shardingsphere focusing on business value, maintainability, and performance improvements across the codebase. Delivered structural refactors and quality enhancements with clear impact on reliability and delivery velocity. Notable outcomes include a SQL Token and Statement Compiler refactor that tightens typing for SQLTokenGenerator and overhauls SQLStatementCompilerEngine, enabling safer, more maintainable SQL parsing pipelines. Widespread code formatting cleanups improved readability and reduced drift. Security posture was strengthened through native profile enablement for jdbc-distribution, dependency upgrades (e.g., commons-io 2.20.0), and targeted CVE mitigations (CVEs 2024-7254 and 2025-48924), along with removing unused dependencies in Calcite. Major architectural work restructured transaction management by introducing shardingsphere-transaction-* modules and reorganizing dependency management to improve startup performance and runtime footprint. Testing infrastructure was enhanced with transaction profiles, parameterized tests, and modern Awaitility usage, increasing reliability and coverage. SQL parsers were refactored and consolidated (SQLServerPropertiesParser, Hive/MySQL parsers) to improve maintainability and consistency across the SQL engine. Additional improvements included logging, build hygiene, and documentation updates to align with the evolving module structure. Overall, these efforts reduce risk, accelerate feature delivery, and lay a scalable foundation for future capabilities.

Jun 1, 2025June 2025 highlights substantial architectural modernization and feature delivery in apache/shardingsphere. The main focus was on refactoring the SQL statement model for TCL/RL/DCL/DAL/DML/DDL to improve structure, consistency, and maintainability, enabling safer cross-dialect evolution. Key architectural improvements included unifying transaction semantics with XA-based statements and consolidating Begin/Start, Commit/Prepare flows across databases; consolidating and renaming statement contexts to TableAvailableSQLStatementContext and related contexts, while removing deprecated contexts to simplify the surface area. These changes improve cross-dialect consistency, reduce risk for new features, and speed future development. Several business-value features were delivered through modular expansion and refactors: add Infra Route modules for route infrastructure; introduce sharding-dialect and rewrite modules to enable rewrite capabilities; implement SQLBindEngine support for SQL Server and PostgreSQL; move PostgreSQL TCL visitor and checkpoint handling to the DAL; migrate many statements to the DAL layer for consistency; and introduce a comprehensive SQLStatementAttribute framework to enrich metadata extraction. In total, the month delivered a foundation for scalable, cross-dialect capabilities and improved performance/maintainability.

Jan 1, 2025January 2025 (apache/shardingsphere) delivered a sweeping event-driven architecture refactor and core modularization that unlocks faster change cycles and greater stability. Key features delivered include: 1) Event Dispatch and Handler Infrastructure Refactor, introducing new event dispatch handler components, reorganizing cluster.dispatch, and replacing legacy subscribers/builders with Handler-based patterns (DeliverEventSubscriber, MetaDataChangedHandler, RuleConfigurationChangedHandler, QualifiedDataSourceChangedHandler, MetaDataContextHolder, ClusterEventSubscriberRegistry). Notable commits include adding the event.dispatch.handler.global package and migrating related handlers. 2) Dispatch Event Cleanup and Deprecation, removing deprecated DispatchEvent components and trailing cleanup (DispatchEventBuilder, useless DispatchEvent, cached subscriber) and relocating dispatch artifacts. 3) Refactor and restructure tests and core components, including SwitchingTransactionRuleTestCase, DatabaseMetaDataNode, ComputeNodePath, ProcessNodePath, and QualifiedDataSourceNodePath, with corresponding registry and test updates. 4) Metadata/core modernization and modularization, including merging metadata-core and mode-core into a single core module; moving DeliverEventSubscriberRegistry to mode-core; GlobalNodePath restructuring; modularization of mode-* modules; and introduction of mode-manager.build. 5) API cleanups and quality improvements, removing deprecated version persistence services (MetaDataVersionPersistService, MetaDataVersionBasedPersistService); adding ActiveVersionChecker; updates to release notes; and code quality improvements (final on RuleItemManager) alongside support for shared components in common modules. 6) Stability improvements and e2e fixes, addressing end-to-end agent errors, native image reflection issues, and sonar/test cleanups. The month culminated in a more maintainable, modular, and testable foundation ready for faster feature delivery and more reliable operations.
