Expanded events table

Version
2.0.58

Release Date

February 26, 2021

Key Features

The "expanded" event store table increases convenience, performance, and cost-effectiveness of large-scale behavioral queries.

Details

All UDP instances now contain a new table in the , called "expanded," that aggressively expands its representation of a Caliper event in tabular form. The new "expanded" table lives alongside the "events" table in the "event_store" dataset of each UDP instance. The "expanded" table explodes the contents of Caliper events –including the JSON blob and JSON nodes– into separate columns of a single Caliper event record.

Additional features of the new "expanded" table include:

  • A more complete representation of a Caliper event's identifiers for Person and Course offering using the . The "expanded" tables will make it easier to use the given identifiers in an Event and the learning tool identifiers that are parsed from an event's IRIs or retrieved from the .

  • The date and time (e.g., "16:00") components of the event's timestamp are now separated into distinct columns.

  • Canvas events now have a consistent, singular "ed_app" value, making it easier to identify Canvas events.

Please visit our , where you can also find information about how to . We also provide a .

Known Issues

The data in the "expanded" table begins on 2/26/2021. In a forthcoming release, Unizin will backfill behavioral data from each institution's "events" table into its "expanded" table.
