Autonomous components that trigger on non-newspaper batches
- Asger Askov Blekinge
This is the design documentation for autonomous components that trigger on non-newspaper batches
The concept of a Batch is anything kind of object, which tracks events and which autonomous components can trigger on. The Newspaper Batch is a kind of object having these properties as representing a package of scanned newspapers.
Each Batch must have an EVENTS datastream.
In the SBOI Index, these fields will be indexed for each Batch
| Name | Description |
|---|---|
| id | The id of the batch, ie. B44000..-RT2 or edition name |
| doms_uuid | The doms pid of the corresponding record |
| doms_type | repeatable. The doms content models |
| success_event | repeatable. The successful events in the history of this batch |
| fail_event | repeatable. The failed events in the history of this batch |
| initial_date | The creation timestamp of this batch. |
| last_modified | The timestamp of the last modification, however you define this, of this batch |
| timestampFor<eventName> | The (latest) timestamp for the event of the given name |
An Autonomous Component will be configured with these properties
| Name | Description |
|---|---|
| pastSuccessfulEvents | Applicable batches must have these events as success |
| pastFailedEvents | Applicable batches must have these events as failure |
| futureEvents | Applicable batches must not have these events |
| types | Applicable batches must have all these types |
| disallowedTypes | Applicable batches mut not have these types |
| extra Query | Additional query terms to add |
For (normal) autonomous components working on newspaper batches, the extra query terms will not be used.
For components needing to trigger on objects that have changed since the last event of a given name, this extra query should be used
"last_modified > timestampFor<eventName>"
