case class SerializedOffset(json: String) extends Offset with Product with Serializable

Used when loading a JSON serialized offset from external storage. We are currently not responsible for converting JSON serialized data into an internal (i.e., object) representation. Sources should define a factory method in their source Offset companion objects that accepts a SerializedOffset for doing the conversion.

    Equality based on JSON string representation.

    Equality based on JSON string representation. We leverage the JSON representation for normalization between the Offset's in memory and on disk representations.

    A JSON-serialized representation of an Offset that is used for saving offsets to the offset log.

    A JSON-serialized representation of an Offset that is used for saving offsets to the offset log. Note: We assume that equivalent/equal offsets serialize to identical JSON strings.
