> jobGraph.setSnapshotSettings(settings) 
> {code:java}
> private void configureCheckpointing() 
> CheckpointConfig cfg = streamGraph.getCheckpointConfig(); long interval = cfg.getCheckpointInterval(); if (interval < MINIMAL_CHECKPOINT_TIME) { // interval of max value means disable periodic checkpoint interval = Long.MAX_VALUE; }
