Incremental checkpoint has been adopted widely in industry community for many years , and it is also well-tested from the feedback in the community discussion. Incremental checkpointing is more light-weighted: shorter checkpoint duration, less uploaded data and less resource consumption. > > In terms of backward compatibility, enable incremental checkpointing would not make any data loss no matter restoring from a full checkpoint/savepoint or an incremental checkpoint. > > FLIP-193 (Snapshot ownership)[1] has been released in 1.15, incremental checkpoint no longer depends on a previous restored checkpoint in default NO_CLAIM mode, which makes the checkpoint lineage much cleaner, it is a good chance to change the configuration state.backend.incremental to true as default. > > Thus, based on the above discussion, I suggest to make state.backend.incremental as true by default.
