Field Detail

isRealThrift

protected boolean isRealThrift

Indicates whether fields can be out of order or missing. i.e., is it really real thrift serialization. This is used by dynamicserde to do some optimizations if it knows all the fields exist and are required and are serialized in order. For now, those optimizations are only done for DynamicSerDe serialized data so always set to false for now.

fieldsPresent

protected boolean[] fieldsPresent
