configurableOptions

org.apache.flink.configuration.ReadableConfig configurableOptions

The configurable options.

enableIncrementalCheckpointing

org.apache.flink.util.TernaryBoolean enableIncrementalCheckpointing

This determines if incremental checkpointing is enabled.

incrementalRestoreAsyncCompactAfterRescale

org.apache.flink.util.TernaryBoolean incrementalRestoreAsyncCompactAfterRescale

Whether we trigger an async compaction after restores for which we detect state in the database (including tombstones) that exceed the proclaimed key-groups range of the backend.

localRocksDbDirectories

manualCompactionConfig

RocksDBManualCompactionConfig manualCompactionConfig

memoryConfiguration

RocksDBMemoryConfiguration memoryConfiguration

The configuration for memory settings (pool sizes, etc.).

nativeMetricOptions

RocksDBNativeMetricOptions nativeMetricOptions

The default rocksdb property-based metrics options.

numberOfTransferThreads

int numberOfTransferThreads

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

overlapFractionThreshold

double overlapFractionThreshold

The threshold of the overlap fraction between the handle's key-group range and target key-group range.

predefinedOptions

PredefinedOptions predefinedOptions

The pre-configured option settings.

priorityQueueConfig

RocksDBPriorityQueueConfig priorityQueueConfig

The configuration for rocksdb priorityQueue state settings (priorityQueue state type, etc.).

rescalingUseDeleteFilesInRange

org.apache.flink.util.TernaryBoolean rescalingUseDeleteFilesInRange

Whether to leverage deleteFilesInRange API to clean up useless rocksdb files during rescaling.

rocksDBMemoryFactory

RocksDBMemoryControllerUtils.RocksDBMemoryFactory rocksDBMemoryFactory

Factory for Write Buffer Manager and Block Cache.

rocksDbOptionsFactory

RocksDBOptionsFactory rocksDbOptionsFactory

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

useIngestDbRestoreMode

org.apache.flink.util.TernaryBoolean useIngestDbRestoreMode

Whether we use the optimized Ingest/Clip DB method for rescaling RocksDB incremental checkpoints.

writeBatchSize

long writeBatchSize

Max consumed memory size for one batch in RocksDBWriteBatchWrapper, default value 2mb.
