> ===================================
> I'm currenlty solving it by reading the original file and appending it to a
> new Vec
> {code:java}
> let bytes: Vec<u8> = object_store
> .get(&old_manifest_location)
> .await?
> .bytes()
> .await?
> .into();
> let mut writer = apache_avro::Writer::new(&schema, Vec::new());
> let reader = apache_avro::Reader::new(&*bytes)?;
> writer.extend(reader.filter_map(Result::ok))?;
> writer.append_ser(entry)?;
> let new_bytes = writer.into_inner()?;
> {code}
> I was wondering if I could do something like:
> {code:java}
> let bytes: Vec<u8> = object_store
> .get(&old_manifest_location)
> .await?
> .bytes()
> .await?
> .into();
> let mut writer = apache_avro::Writer::new(&schema, bytes);
> writer.append_ser(entry)?;
> let new_bytes = writer.into_inner()?;
> {code}
