Function cdc::delegate::decode_write

fn decode_write(
    key: Vec<u8>, 
    value: &[u8], 
    row: &mut EventRow, 
    is_apply: bool
) -> bool

Decodes the write record and store its information in row. This may be called both when doing incremental scan of observing apply events. There’s different behavior for the two case, distinguished by the is_apply parameter.
