Data snapshots jobs and tables
Several types of components are installed with activation of the Data snapshots plugin, including tables and scheduled jobs.
Scheduled jobs installed
|
Scheduled job |
Description |
|---|---|
|
Instance Eligibility Check Job for Data Snapshots |
Daily job to check whether the instance is eligible for the Data snapshots feature. If so, Data snapshots are enabled on the instance. If you want to disable the Data snapshots feature, deactivate this job. |
|
Instance readiness for Data snapshots |
On demand job to enable Data snapshots for an instance. Called by the Instance Eligibility Check job for Data Snapshots. |
The following jobs are defined on the Scheduled Data Collections [sysauto_dm_cdc_collector] table. These jobs populate Data snapshots indicators with scores.
| Scheduled data collection | Description |
|---|---|
| First snapshot | Sets up the initial data for analysis by capturing the current state of the fact table. It runs one time, when a Data snapshots source is set up. It collects a snapshot of the facts table to prepare the system for daily updates. |
| Incremental all changes snapshots | Runs every 30 minutes on Data snapshots indicators whose data frequency is All changes. |
| Incremental daily snapshot | Runs every hour on Data snapshots sources whose frequency is Daily. Updates the final fact table once a day with the last change. |
To see how much time each job took, find the job in the Data Snapshots Statistics [pa_dm_task_telemetry] table. Navigate to this table at Platform Analytics Administration > Data Collector > Data Snapshots Job Logs.
To see the details of each job that was run on a Data Snapshots data source, open the data source [pa_dm_analytics_source] at Platform Analytics Administration > Data Sources > Data Snapshots. The logs are listed in the Data Snapshots Logs related list. For more information, see Data snapshots logs.
