Hi all!
For some reason I haev to know much more about the parquet format. Meanwhile I
know the column chunk can be found at
FileMetaData.row_groups[x].columns[x].file_offsetIf I compreheded all right at
file_offset starts the repetition level array followed by the definition leve
array followed by thecolumn values. Is there a way
to skip both arrays and to go directly to tha values? How long are both
arrays? I would read them. But how? All I know is: They areBitPacked.. So I
expect there is a MAX VALUE field or perhaps a BITS_PER_VALUE field and if it
is 3 then
7 2 1 0 3
is coded
111010001000011
But where is MAX-VAUE or BITS_PER_VALUE ?
An URL or pointer to a line in some C (++) or Java code would suffice.
Thank you in advance
Jörg
