Enum OracleConnectorConfig.SnapshotMode

    • Enum Constant Detail

      • INITIAL_ONLY

        public static final OracleConnectorConfig.SnapshotMode INITIAL_ONLY
        Perform a snapshot of data and schema upon initial startup of a connector and stop after initial consistent snapshot.

      • SCHEMA_ONLY_RECOVERY

        public static final OracleConnectorConfig.SnapshotMode SCHEMA_ONLY_RECOVERY
        Perform a snapshot of only the database schemas (without data) and then begin reading the redo log at the current redo log position. This can be used for recovery only if the connector has existing offsets and the database.history.kafka.topic does not exist (deleted). This recovery option should be used with care as it assumes there have been no schema changes since the connector last stopped, otherwise some events during the gap may be processed with an incorrect schema and corrupted.

    • Method Detail

      • values

        public static OracleConnectorConfig.SnapshotMode[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (OracleConnectorConfig.SnapshotMode c : OracleConnectorConfig.SnapshotMode.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static OracleConnectorConfig.SnapshotMode valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null

      • includeData

        public boolean includeData()
        Whether this snapshotting mode should include the actual data or just the schema of captured tables.

      • shouldStream

        public boolean shouldStream()
        Whether the snapshot mode is followed by streaming.

      • shouldSnapshotOnSchemaError

        public boolean shouldSnapshotOnSchemaError()
        Whether the schema can be recovered if database history is corrupted.

      • parse

        public static OracleConnectorConfig.SnapshotMode parse​(String value)
        Determine if the supplied value is one of the predefined options.
        Parameters:
        value - the configuration property value; may not be null
        Returns:
        the matching option, or null if no match is found

      • parse

        public static OracleConnectorConfig.SnapshotMode parse​(String value,
                                                       String defaultValue)
        Determine if the supplied value is one of the predefined options.
        Parameters:
        value - the configuration property value; may not be null
        defaultValue - the default value; may be null
        Returns:
        the matching option, or null if no match is found and the non-null default is invalid
