org.teiid.translator.DataNotAvailableException

All Implemented Interfaces:

Serializable

public class DataNotAvailableException
extends TeiidRuntimeException

Used by asynch connectors to indicate data is not available and results should be polled for after the given delay in milliseconds or until a Date is reached.
Note that delays are not guaranteed unless strict is set to true. With strict false, the delay is the maximum amount of time before the plan will be re-queued for execution. There are several scenarios that would cause the delay to be shorter, such as multiple sources where one source returns a shorter delay or if the engine believes more work is to be done before allowing the plan to sit idle.
