Claim: Apache Flink includes a lightweight fault tolerance mechanism based on distributed checkpoints, and in the case of a failure, a Flink program with checkpointing enabled will, upon recovery, resume processing from the last completed checkpoint, and Flink also includes a mechanism called savepoints, which are manually-triggered checkpoints.
Evidence: Apache Flink includes a lightweight fault tolerance mechanism based on distributed checkpoints. In the case of a failure, a Flink program with checkpointing enabled will, upon recovery, resume processing from the last completed checkpoint, ensuring that Flink maintains exactly-once state semantics within an application. Flink also includes a mechanism called savepoints, which are manually-triggered checkpoints.
