Review Comment: let mut bytes_copy = bytes.clone() for Payload::Raw is unnecessary. ConsumedMessage is moved into prepare_document(), so bytes is already owned. simd_json requires &mut [u8]. **Fix**: let Payload::Raw(mut bytes) = payload, pass &mut bytes directly, use bytes for base64 fallback. Eliminates full payload clone per raw message. -- This is an automated message from the Apache Git Service.
