Batch Tracker Backfill

The Batch Tracker Backfill object (also referred to as the Backfill Controller) is created below the Batch Tracker and used to configure a selective and on-demand reprocessing of historical data over a defined time period. Any missing data for that time period is backfilled by the Batch Tracker and added to the BPR (Batch Production Record). This Backfill Mode is turned on by changing the Mode from "Configuration" to "Running". The configuration of the time period is done via Starttime and Endtime properties and this time period can be updated at any point. A BatchID Filter can also be entered which will only retrieve records for a matching BatchID string. Multiple Batch Tracker Backfill objects can be configured below one Batch Tracker. The Backfill process can be followed.

The Batch Tracker Backfill object and Backfill Mode requires that all Tags configured in the parent Batch Tracker be set to historize data in a configured data store Archive Selector .

Use Cases

Backfill missing data from running Batch Trackers objects
Selectively backfill data for particular BatchIDs in advance or on the fly
Automate the backfill process by updating backfill time period and triggering the mode

Quick Configuration

Select the parent BatchTracker object and right-click. Select Admin New Production Tracking Backfill Controller from the context menu.
In the Create Object wizard, enter an Object name and an optional Object Description.
Open the Starttime time/date picker and select a start for the time period you wish to cover. Do the same with Endtime to select the end of the desired time period.
If you wish to only backfill data for a particular BatchID, enter the BatchID as a string in the BatchID Filter property field (optional).
Click Create to create the object in the I/O Model.
To begin backfilling data, select the object in the I/O Model and change the Mode property in the Object Properties panel from "Configuration" to "Running" and click Apply.
The progress of the backfill operation can be followed in the Diagnostics compound which details information on the state of the process, including information from the Batch Tracker. The Tracking Documents compound allows the actual backfilled BPR documents to be viewed in JSON format (the last completed and the currently processed BPRs).
Once the backfill for the specified time period is completed then the Mode will change back to "Configuration". The backfill operation can be re-run at any time to fill in any extra missing information.

Running: This setting will start the operation.

Progress: Progress indicator for the backfill operation.

Attachments: File attachments stored in MongoDB file store.

Tracking Documents

The persisting JSON documents for the active and recently completed batch.

Recently Completed: JSON document for the most recent completed batch.

Completed at: The time when the recent batch was completed.

Current: JSON document for the current batch.

Last Update: The time when the current batch recently was updated.

Last run: timestamp of the last run.
