This is a learning collection of example projects that demonstrate core Spring Cloud patterns for building microservice architectures. The repository covers the fundamental building blocks of a microservices system, including service discovery through a central registry, centralized configuration management from Git or SVN repositories, API gateway-based request routing, circuit breaker patterns for fault tolerance, and distributed request tracing across service boundaries. The examples show how to implement service registration and dynamic discovery so that clients can locate microservices b
Demonstrates connecting to and querying multiple MySQL instances within a single application.
ServiceStack is a high-performance .NET web framework designed for building type-safe APIs using strongly-typed request and response objects. It functions as a message-based API engine that decouples business logic from the transport layer, allowing services to be exposed via multiple protocols including HTTP, gRPC, and various message queue providers. The framework is distinguished by its type-safe API generator, which produces native client SDKs and data transfer objects from service metadata across multiple languages. It also includes a distributed service gateway for microservices orchest
Provides a unified interface to query across relational databases, in-memory collections, and NoSQL tables.
Octosql هو محرك استعلامات SQL موزع، ومحول بيانات، ومعالج SQL للبث المباشر. يتيح للمستخدمين تنفيذ استعلامات SQL واحدة عبر مصادر بيانات متعددة ومتباينة، بما في ذلك أنواع قواعد البيانات المختلفة وتنسيقات الملفات، لدمج النتائج وتحويلها إلى مجموعة بيانات موحدة. يتميز النظام بمعاملة ملفات CSV وJSONLines وParquet كجداول افتراضية، ويستخدم بنية تعتمد على الإضافات (plugins) لتوسيع الاتصال بمحركات التخزين الخارجية. يعمل كمعالج للبث المباشر لتدفقات البيانات غير المحدودة، مستخدماً العلامات المائية (watermarks) وعمليات التراجع (retractions) والنوافذ الزمنية (tumbling windows) للحفاظ على الاتساق في الأحداث غير المرتبة. بالإضافة إلى ذلك، يعمل كمولد بيانات SQL قادر على إنتاج مجموعات بيانات اصطناعية وتدفقات سجلات عبر دوال ذات قيم جدولية. يتضمن المحرك قدرات لربط البيانات عبر مصادر متعددة والتحليل متعدد المصادر، مع تحسين الأداء عبر دفع التنبؤات (predicate push-down) إلى جانب المصدر لتقليل نقل البيانات. يدير النظام البيانات المعقدة من خلال نظام أنواع ثابت (static type system) مع أنواع اتحادية (union types) ويوفر إمكانية المراقبة عبر تصور خطط تنفيذ الاستعلامات.
Runs single SQL statements across diverse databases to merge data from different origins into a unified view.
Querydsl is a framework for the construction of type-safe queries. It uses a fluent API and annotation-based code generation to create mirror classes from domain models, enabling compile-time validation of database queries and removing the need for manual string concatenation. The project provides a unified query syntax that translates into specific dialects for multiple backends, including SQL, MongoDB, Lucene, and JDO. It supports advanced query capabilities such as common table expressions, window functions, geospatial operations, and complex nested subqueries. Beyond data retrieval, the
Executes select queries with support for filtering across multiple data sources, subqueries, and various join types.
Franchise is a database query tool and notebook SQL client that allows users to run queries and analyze datasets. It functions as a local data processor with a browser-based engine for executing SQL commands against CSV, JSON, and XLSX files without uploading data to a remote server. The project uses a cell-based interface to organize queries and results in an interactive, document-like layout. It supports a workflow where users can fork queries into side-by-side layouts to compare different SQL variations and their results without overwriting existing code. The system provides a unified int
Enables running SQL queries across a diverse set of local files and remote database instances from a single interface.
