The message flow between the adapter and an HTTP client is initiated when the client sends a POST request with the start command in it, and a body consisting of a SQL query, to Event Stream Processor.
Changes in the corresponding stream are pulsed back to the HTTP client as XML-formatted chunk-coded HTTP responses.
Specify the pulse interval in the adapter configuration. In the event of a failover, the SDK API switches, as configured, to the spare Event Stream Processor instance without message loss.
