OVERVIEW\n\n\u003Chr>\n\nApache ShardingSphere is positioned as **Database Plus**, a standard and ecosystem built on top of heterogeneous databases. As an operating system layer above databases, ShardingSphere does not create new databases but focuses on maximizing the computing capabilities of existing databases, providing unified data access and enhanced computing capabilities.\n\n**Database Plus Core Concept**: By building a standardized and scalable enhancement layer above databases, it makes heterogeneous databases as simple to use as a single database, providing unified governance capabilities and distributed computing capabilities for enterprise data architectures.\n\n**Connect, Enhance, and Pluggable** are the three core pillars of Apache ShardingSphere:\n\n- **Connect:** Building database upper-layer standards, quickly connecting applications with multi-modal heterogeneous databases through flexible adaptation of database protocols, SQL dialects, and storage formats, providing unified data access experience;\n\n- **Enhance:** As a database computing enhancement engine, transparently providing enterprise-grade capabilities including distributed computing (data sharding, readwrite-splitting, SQL federation), data security (encryption, masking, audit), traffic control (circuit breaker, rate limiting), and observability (monitoring, tracing, analysis);\n\n- **Pluggable:** Adopting a micro-kernel + 3-layer pluggable architecture to achieve complete decoupling of kernel, functional components, and ecosystem integration. Developers can flexibly customize unique data architecture solutions that meet enterprise needs, just like building with LEGO blocks.\n\n**Differentiation Advantages**:\n- **vs Distributed Databases**: More lightweight, protecting existing investments, avoiding vendor lock-in\n- **vs Traditional Middleware**: Richer features, more complete ecosystem, more flexible architecture\n- **vs Cloud Vendor Solutions**: Support multi-cloud deployment, avoid technology binding, autonomous and controllable\n\nShardingSphere became an [Apache](https:\u002F\u002Fapache.org\u002Findex.html#projects-list) Top-Level Project on April 16, 2020, and has been adopted by [19,000+ projects](https:\u002F\u002Fgithub.com\u002Fsearch?l=Maven+POM&q=shardingsphere+language%3A%22Maven+POM%22&type=Code) worldwide.\n\n### DUAL-ACCESS ARCHITECTURE DESIGN\n\n\u003Chr>\n\nShardingSphere adopts a unique dual-access architecture design, providing two access ends - JDBC and Proxy - that can be deployed independently or in hybrid deployment, meeting diverse requirements for different scenarios.\n\n#### ShardingSphere-JDBC: Lightweight Access End\n\n**Positioning**: Lightweight Java framework, enhanced JDBC driver\n\n**Core Features**:\n- **Client-side direct connection**: Shares resources with applications, decentralized architecture\n- **High performance, low overhead**: Direct database connection with minimal performance loss\n- **Complete compatibility**: Compatible with all ORM frameworks (MyBatis, JPA, Hibernate, etc.)\n- **Zero additional deployment**: Provided as JAR package, no independent deployment and dependencies required\n\n**Use Cases**: High-performance Java applications, integrated deployment with business applications, pursuing ultimate performance\n\n#### ShardingSphere-Proxy: Enterprise Access End\n\n**Positioning**: Transparent database proxy, independently deployed server-side\n\n**Core Features**:\n- **Static entry point**: Independent deployment from applications, providing stable database access entry\n- **Heterogeneous language support**: Supports any MySQL\u002FPostgreSQL protocol compatible client\n- **DBA friendly**: Database operation and maintenance management interface, convenient for O&M personnel\n- **Enterprise-grade features**: Supports cluster deployment, load balancing, failover\n\n**Use Cases**: Heterogeneous language environments, database operation and maintenance management, enterprise applications requiring unified access entry\n\n#### Hybrid Architecture Advantages\n\nBy hybridizing ShardingSphere-JDBC and ShardingSphere-Proxy with unified configuration through the same registry center, you can flexibly build application systems suitable for various scenarios:\n\n- **Architectural flexibility**: Architects can freely adjust the optimal system architecture\n- **Scenario adaptability**: Select the most suitable access method according to different business scenarios\n- **Unified management**: Single configuration, multi-end collaboration, simplifying O&M complexity\n- **Progressive evolution**: Support smooth evolution path from JDBC to Proxy\n\n### AI

Antlr uses an internal cache to improve performance during SQL parsing. If your application has too many SQL templates, the cache will continue to grow, occupying a large amount of heap memory.\nAccording to feedback from the ANTLR official [issue#4232](https:\u002F\u002Fgithub.com\u002Fantlr\u002Fantlr4\u002Fissues\u002F4232), this issue has not yet been optimized. When connecting your application to ShardingSphere-JDBC, it is recommended to set a reasonable heap memory size using the `-Xmx` parameter to avoid OOM errors caused by insufficient memory.\n\n### ShardingSphere-Proxy\n\n\u003Chr>\n\n[![Nightly-Download](https:\u002F\u002Fimg.shields.io\u002Fstatic\u002Fv1?label=nightly-builds&message=download&color=orange)](https:\u002F\u002Fnightlies.apache.org\u002Fshardingsphere\u002F)\n[![Download](https:\u002F\u002Fimg.shields.io\u002Fbadge\u002Frelease-download-orange.svg)](https:\u002F\u002Fwww.apache.org\u002Fdyn\u002Fcloser.lua\u002Fshardingsphere\u002F5.3.2\u002Fapache-shardingsphere-5.3.2-shardingsphere-proxy-bin.tar.gz)\n[![Docker

transparent database proxy, providing a database server that encapsulates the database binary protocol to support heterogeneous languages. \nFriendlier to DBAs, the MariaDB, MySQL and PostgreSQL version now provided can use any kind of terminal.\n\n:link: For more details, follow this [link to the official website](https:\u002F\u002Fshardingsphere.apache.org\u002Fdocument\u002Fcurrent\u002Fen\u002Foverview\u002F#shardingsphere-proxy).\n\n### Hybrid Architecture\n\n\u003Chr>\n\nShardingSphere-JDBC adopts a decentralized architecture, applicable to high-performance light-weight OLTP applications developed with Java. \nShardingSphere-Proxy provides static entry and all languages support, suitable for an OLAP application and sharding databases management and operation.\n\nThrough the combination of ShardingSphere-JDBC & ShardingSphere-Proxy together with a unified sharding strategy by the same registry center, the ShardingSphere ecosystem can build an application system suitable to all kinds of scenarios.\n\n:link: More details can be found following this [link to the official website](https:\u002F\u002Fshardingsphere.apache.org\u002Fdocument\u002Fcurrent\u002Fen\u002Foverview\u002F#hybrid-architecture).\n\n##\n\n### CORE FEATURE MATRIX\n\n\u003Chr>\n\n#### Distributed
