Adapters progress through a set of run states (RS) as they interact
with Event Stream Processor.
- RS_READY – indicates that the adapter is ready to be started.
- RS_INITIAL – indicates that the adapter is performing start-up and initial loading.
- RS_CONTINUOUS – indicates that the adapter is continuously waiting for additional data.
- RS_IDLE – indicates that the adapter has timed out or is attempting to restore a broken socket.
- RS_DONE – indicates when the adapter no longer returns data and can no longer retrieve data following the poll period.
- RS_DEAD – indicates that the adapter has entered the exited state.
When polling is enabled, an input adapter may change states between RS_CONTINUOUS and
RS_IDLE.
