> With the current implementation, {{RawSnapshotReader}} are created and closed by the {{KafkaRaftClient}} as needed to satisfy {{FetchSnapshot}} requests. This means that for {{FileRawSnapshotReader}} they are closed before the network client has had a chance to send the bytes over the network.
> One way to fix this is to make the {{KafkaMetadataLog}} the owner of the {{FileRawSnapshotReader}}. Once a {{FileRawSnapshotReader}} is created it will stay open until the snapshot is deleted by {{ReplicatedLog::deleteBeforeSnapshot}}.
