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>)
Boolean type index
INT32(NativeIndex<i32>)
32-bit integer type index
INT64(NativeIndex<i64>)
64-bit integer type index
INT96(NativeIndex<Int96>)
96-bit integer type (timestamp) index
FLOAT(NativeIndex<f32>)
32-bit floating point type index
DOUBLE(NativeIndex<f64>)
64-bit floating point type index
BYTE_ARRAY(NativeIndex<ByteArray>)
Byte array type index
FIXED_LEN_BYTE_ARRAY(NativeIndex<FixedLenByteArray>)
Fixed length byte array type index
