LLL.DurableTask.EFCore provides relational database storage for Durable Task using Entity Framework Core (EFCore). This implementation leverages row locking, skip locked, and polling to create reliable and efficient task queues.
In addition to the standard features offered by the Durable Task framework, LLL.DurableTask.EFCore includes the following enhancements:
| Feature | Description |
|---|---|
| Distributed workers | Distribute your orchestrations and activities across multiple microservices, each dedicated to specific types of tasks. These microservices connect to a shared database and collaboratively execute tasks to complete workflows efficiently and reliably. |
| Store all inputs/outputs | All inputs and outputs are stored as workflow events. This enhances visibility into the workflow's execution through the UI and supports a more robust rewind algorithm. |
| Improved rewind | We have implemented an advanced rewind algorithm. For more details, refer to this comment. |
| Tags | Orchestration tags are persisted and displayed in the UI, providing better workflow organization and tracking. |
| State per execution | The state of each execution of a workflow instance is preserved, allowing you to view all executions in the UI. |
| Guaranteed Event Delivery | Orchestrations reopen when they receive events, ensuring that no events are missed. This allows you to implement reliable orchestrations without needing to use "eternal orchestrations" via continue-as-new. More information is available at this pull request. |
