Flink error while getting state
WebJul 4, 2024 · For Flink’s stateful stream processing, we differentiate between two different types of state: operator state and keyed state. Operator state is scoped per parallel instance of an operator (sub-task), and keyed state can be thought of as “operator state that has been partitioned, or sharded, with exactly one state-partition per key”. WebIn STREAMING mode, Flink uses a StateBackend to control how state is stored and how checkpointing works. In BATCH mode, the configured state backend is ignored. Instead, the input of a keyed operation is grouped by key (using sorting) and then we process all records of a key in turn.
