object RocksDBStateEncoder extends Logging

Factory object for creating state encoders used by RocksDB state store.

The encoders created by this object handle serialization and deserialization of state data, supporting both key and value encoding with various access patterns (e.g., prefix scan, range scan).

  9. def getKeyEncoder(dataEncoder: RocksDBDataEncoder, keyStateEncoderSpec: KeyStateEncoderSpec, useColumnFamilies: Boolean): RocksDBKeyStateEncoder

    Creates a key encoder based on the specified encoding strategy and configuration.

    Creates a key encoder based on the specified encoding strategy and configuration.

    dataEncoder

    The underlying encoder that handles the actual data encoding/decoding

    keyStateEncoderSpec

    Specification defining the key encoding strategy (no prefix, prefix scan, or range scan)

    useColumnFamilies

    Whether to use RocksDB column families for storage

    returns

    A configured RocksDBKeyStateEncoder instance

  10. def getValueEncoder(dataEncoder: RocksDBDataEncoder, valueSchema: StructType, useMultipleValuesPerKey: Boolean): RocksDBValueStateEncoder

    Creates a value encoder that supports either single or multiple values per key.

    Creates a value encoder that supports either single or multiple values per key.

    dataEncoder

    The underlying encoder that handles the actual data encoding/decoding

    valueSchema

    Schema defining the structure of values to be encoded

    useMultipleValuesPerKey

    If true, creates an encoder that can handle multiple values per key; if false, creates an encoder for single values

    returns

    A configured RocksDBValueStateEncoder instance
