Expand description

Typed statistics for a data page in a column chunk. This structure is obtained from decoding the ColumnIndex in the parquet file and can be used to skip decoding pages while reading the file data.

Variants§

§

NONE

Sometimes reading page index from parquet file will only return pageLocations without min_max index, NONE represents this lack of index information

§

BOOLEAN(NativeIndex<bool>)

§

INT32(NativeIndex<i32>)

§

INT64(NativeIndex<i64>)

§

INT96(NativeIndex<Int96>)

§

FLOAT(NativeIndex<f32>)

§

DOUBLE(NativeIndex<f64>)

§

BYTE_ARRAY(NativeIndex<ByteArray>)

§

FIXED_LEN_BYTE_ARRAY(NativeIndex<FixedLenByteArray>)
