Interface Summary Interface Description CheckpointedFunction This is the core interface for stateful transformation functions, meaning functions that maintain state across individual stream records.ExternallyInducedSource<T,CD> Deprecated. This interface is based on theSourceFunction
API, which is due to be removed.ExternallyInducedSource.CheckpointTrigger Through theCheckpointTrigger
, the source function notifies the Flink source operator when to trigger the checkpoint.ListCheckpointed<T extends Serializable> Deprecated. If you need to do non-keyed state snapshots of your operator, useCheckpointedFunction
.WithMasterCheckpointHook<E> This interface can be implemented by streaming functions that need to trigger a "global action" on the master (in the checkpoint coordinator) as part of every checkpoint and restore operation.
