under the transport in ``messenger.yaml``:

serializer How to serialize the final payload ``Redis::SERIALIZER_PHP``

in Redis (the

``Redis::OPT_SERIALIZER`` option)

stream_max_entries The maximum number of entries which 0 (= no trimming)

the stream will be trimmed to. Be

careful with the configured number
