StreamBase Embedded Adapters

Embedded adapters are those that run in the same EventFlow fragment's engine process that is hosting and processing your EventFlow fragment. In contrast to external adapters, embedded adapters do not incur a client-server communication overhead. Embedded adapters start and stop automatically with the EventFlow fragment.

Alphabetic Listing of all Embedded Adapters

The following embedded adapters are packaged as part of the base StreamBase installation. However, some adapters listed here are Premium adapters that require a separate license, as described on the License Considerations page.

LiveView Adapters

The LiveView embedded adapters allow you to easily configure EventFlow applications that work with LiveView tables. There are five LiveView adapters:

  • The LiveView Query Adapter allows a StreamBase application to register ad hoc queries with LiveView servers and receive snapshot and real-time results.

  • The LiveView Ready Adapter informs a StreamBase application when the configured LiveView Server is ready, and when it changes to not ready.

  • The LiveView Delete Adapter allows a StreamBase application to delete LiveView table rows based on a predicate.

  • The LiveView Publish Output adapter allows a StreamBase application to publish data to LiveView tables.

  • The LiveView Create and Drop Output adapter allows a StreamBase application to interactively create and drop data tables from a running LiveView Server instance.
