Zoomdata Version

Connector Changes

The following connector changes were made in Zoomdata 3:

  • Zoomdata now supports the graceful shutdown of a connector. When a connector is shut down, it gracefully completes queries that are in-flight and notifies clients that the connector is terminating. Three new connector properties have been introduced to support graceful shutdown processing. See Connector Graceful Shutdown.

  • You can now apply the LAST VALUE function when a time-derived field is selected on the time bar and for numeric-derived fields as well. See Connector Feature Support to determine which connectors support the LAST VALUE function and derived fields.

  • The following table describes specific connector changes made in Zoomdata 3.7:
