apshots act as consistent checkpoints to which the system can fall back in case of a failure. Flink's mechanism for drawing these
snapshots is described in "
[
Lightweight Asynchronous Snapshots for Distributed Dataflows

". It is inspired by
the standard
[

)
for distributed snapshots and is
specifically tailored to Flink's execution model.
