    Apache DataFusion is an extensible, columnar SQL query engine that runs embedded within a host application without requiring a separate server process. It processes data in columnar batches using Apache Arrow for memory-efficient analytics, and can scale analytic workloads across multiple nodes for parallel execution. The engine supports both SQL and DataFrame queries through a modular, streaming architecture that allows custom operators, data sources, functions, and optimizer rules. The engine distinguishes itself through its modular extension framework, which enables building custom query e

    本项目是一个 PHP 兼容性 Polyfill,旨在将核心函数和常量从 PHP 7.2 向后移植到旧版本的语言。它作为 PHP 标准库扩展和版本向后移植,提供了一个兼容层,填补了 PHP 核心中的空白,以确保在不同环境中的一致行为。 该库通过实现缺失的标准库函数实现跨版本代码可移植性,允许较新的语言特性在旧版 PHP 环境中运行。这确保了应用能够保持一致的接口,并在运行于过时版本时仍能与当前库保持兼容。

    Allows adding custom functions to an expression engine by registering providers.

    FreeSql 是一个 .NET 对象关系映射器(ORM)和数据访问层,可将面向对象的代码转换为适用于多种关系型数据库提供程序的 SQL。它作为一个流畅的 SQL 查询构建器和数据库架构同步器,允许开发者将数据库表和索引结构与实体类定义保持一致。 该框架专门针对 .NET Native AOT 进行了优化,以确保更小的内存占用和更快的启动时间。它包含一个数据库流量管理器,通过读写分离、动态分表和基于租户的数据隔离来分配负载。 其广泛的功能包括使用特定于提供程序的批量复制机制实现高性能数据摄入,利用窗口函数和递归 CTE 进行高级查询,以及基于 AOP 的数据变更审计监控。该系统还提供用于自动迁移的架构管理工具,以及用于从数据库元数据生成实体类的开发实用程序。

  • Custom Expression ProvidersAllows registering custom providers to map expression calls to specific logic. **Distinct from Expression Functions:** Focuses on the extensibility (registration) of the functions rather than the predefined set of functions.
  • Extension Method MappingMaps programming extension methods to database-specific functions in queries. **Distinct from Expression Functions:** Distinct from Expression Functions by focusing on the mapping of high-level extension methods to SQL.
