trait KryoFeatureSerializer extends KryoFeatureSerialization with KryoFeatureDeserialization

Kryo feature serialization and deserialization.

The current serialization scheme (version 3):

  • one byte containing the serialization version (3)
  • two bytes for a short containing the number of serialized attributes. this supports appending attributes to the schema, as we know how many attributes were written when deserializing
  • one byte for the size of the stored offsets, which will currently be either 2 (for shorts) or 4 (for ints)
  • a known number of bytes for metadata, which consists of:
  • 2 byte short or 4 byte int (determined by the size as stored above) per attribute for the offset to the start of the attribute in the serialized bytes
  • 2 byte short or 4 byte int (determined by the size as stored above) for the offset to the start of the user data (or end of the feature if no user data)
  • 4 bytes per 32 attributes (or part thereof) to store a bitset tracking null attributes
  • the feature id as a string (if withId)
  • the serialized attributes, in order
  • the serialized user data (if withUserData)
