NOTE: checkpoints are generally managed by Flink. This setting isn't meant to replace Flink's checkpoint settings, but to complement them in special cases. For instance, a full checkpoint might need to be occasionally triggered to break the chain of incremental checkpoints and consolidate the partial incremental files. WARNING: not intended to be used together with the cron-based periodic checkpoint triggering
