序列化字段

checkpointStreamBackend

org.apache.flink.runtime.state.StateBackend checkpointStreamBackend

The state backend that we use for creating checkpoint streams.

localRocksDbDirectories

File[] localRocksDbDirectories

Base paths for RocksDB directory, as configured. Null if not yet set, in which case the configuration values will be used. The configuration defaults to the TaskManager's temp directories.

predefinedOptions

PredefinedOptions predefinedOptions

The pre-configured option settings.

optionsFactory

OptionsFactory optionsFactory

The options factory to create the RocksDB options in the cluster.

enableIncrementalCheckpointing

org.apache.flink.util.TernaryBoolean enableIncrementalCheckpointing

This determines if incremental checkpointing is enabled.

numberOfTransferingThreads

int numberOfTransferingThreads

Thread number used to transfer (download and upload) state, default value: 1.

enableTtlCompactionFilter

org.apache.flink.util.TernaryBoolean enableTtlCompactionFilter

This determines if compaction filter to cleanup state with TTL is enabled.

Note: User can still decide in state TTL configuration in state descriptor whether the filter is active for particular state or not.

priorityQueueStateType

RocksDBStateBackend.PriorityQueueStateType priorityQueueStateType

This determines the type of priority queue state.

defaultMetricOptions

RocksDBNativeMetricOptions defaultMetricOptions

The default rocksdb metrics options.
