Quartznet
Quartz.NET is a job scheduler for .NET applications designed to schedule and execute programmatic tasks. It functions as a distributed task orchestrator and enterprise task orchestrator, capable of managing recurring jobs with concurrency limits and complex intervals.
The system provides high availability through a clustered execution model that balances loads and provides fail-over redundancy across multiple server instances. It utilizes a relational database job store to persist job and trigger states, ensuring that scheduled tasks survive application restarts.
The framework includes capabilities for calendar-aware triggering to exclude specific dates and a plugin-based extension model for custom functionality. Event monitoring is handled through listeners that intercept scheduling lifecycles for auditing and system diagnostics.
Configuration is managed via a fluent interface and external files to define operational parameters.
Features
- Job Schedulers - Provides a robust engine for triggering programmatic tasks based on specific times, dates, or recurring intervals.
- Distributed Job Execution - Provides a clustered execution model that distributes tasks across multiple server instances with load balancing and fail-over redundancy.
- Job Schedulers - Provides a comprehensive framework for orchestrating background tasks based on time-based schedules.
- Job State Persistence - Saves job and trigger definitions in memory or relational databases to maintain state across restarts.
- Relational Storage Backends - Enables the use of relational databases as the persistence layer for job and trigger details.
- Task Orchestrators - Implements a system for managing recurring background operations with state tracking, concurrency limits, and extensibility for auditing.
- High Availability Clustering - Distributes scheduled work across multiple instances with automatic fail-over for high availability.
- Job Scheduling - Functions as a dedicated .NET job scheduler for managing and executing background processing jobs.
- Programmatic Job Instantiation - Allows the execution of specialized classes as jobs using flexible instantiation methods.
- Database-Backed Persistence - Utilizes a relational database to persist job and trigger states, ensuring tasks survive application restarts.
- Clustered Task Distribution - Implements a clustered execution model that balances loads and provides fail-over redundancy across server instances.
- Job Execution Filtering - Provides calendar-aware triggering to exclude specific dates and holidays from scheduled task execution.
