Dynamic Datasource
Este proyecto es un gestor de fuentes de datos dinámicas para Spring Boot diseñado para manejar múltiples conexiones de bases de datos y cambiar entre ellas en tiempo de ejecución. Proporciona un sistema para gestionar la división de lectura-escritura de bases de datos, coordinar transacciones distribuidas en bases de datos dispares y actualizar la configuración de conexión sin requerir un reinicio de la aplicación.
El framework se diferencia por su capacidad para enrutar el tráfico según las sesiones o encabezados de usuario para admitir arquitecturas multi-inquilino. También incluye un mecanismo para cifrar credenciales de bases de datos sensibles dentro de archivos de configuración para evitar la exposición en texto plano.
La superficie de capacidades se extiende al enrutamiento de conexiones de bases de datos, división de lectura-escritura entre nodos maestros y esclavos, y la inicialización de conexión diferida para reducir el tiempo de inicio. Además, gestiona la consistencia de los datos a través del control centralizado de transacciones y admite la adición o eliminación en tiempo de ejecución de configuraciones de conexión de bases de datos.
Features
- Spring Boot Database Access - Provides a framework for Spring Boot that handles multiple database connections and switches between them at runtime.
- Runtime Connection Configuration - Enables adding or modifying database connection settings without requiring an application restart.
- Request Routing - Directs requests to specific database groups to support read-write splitting and master-slave replication.
- Runtime Connection Management - Allows programmatically adding, removing, or switching database connection configurations while the application is running.
- Dynamic Connection Switching - Evaluates dynamic parameters from sessions or headers to swap active database connections at runtime.
- Read-Write Splitting - Routes traffic between master and slave databases to optimize performance and load balancing.
- Tenant Request Routing - Directs application requests to different databases based on user sessions or headers to support multi-tenant architectures.
- Multi-datasource Configurators - Provides a system for defining and switching between multiple named database connections within a single application.
- Read-Write Splitting - Optimizes database performance by routing read queries to slave nodes and write queries to the master node.
- Context-Aware Connection Selection - Determines the target database by retrieving routing keys from thread-local storage or request headers.
- Dynamic Proxy Routing - Wraps the data source in a proxy that delegates queries to different physical connections based on the current context.
- Connection Route Switching - Implements AOP-based interception to switch database connections dynamically based on annotations.
- Secure Database Configurations - Protects sensitive database credentials in configuration files using encryption to prevent plain text exposure.
- Lazy Connection Initialization - Delays the creation of database connections until the first request occurs to reduce startup time.
- Lazy Connection Initialization - Postpones the creation of database connection pools until the first request to reduce startup time.
- Runtime Configuration Refreshes - Updates the internal data source map and connection pools without restarting the application when configuration changes.
- Credential Encryption - Protects sensitive connection information in configuration files using built-in or custom encryption methods.
- Distributed Transaction Coordinators - Coordinates commit and rollback operations across multiple data sources by hooking into a distributed transaction coordinator.
