Uwe L. Korn updated PARQUET-820:
--------------------------------
Description: Currently the decoders all emit the data arrays in the form of
the PLAIN encoding, i.e. only the non-null entries with no memory wastage for
null entries. But for random access we need to gap the output so that entry
{{i}} is located at memory address {{base + i * type_size}}.
> C++: Decoders should directly emit arrays with spacing for null entries
